Genesis 20

Verses 1–18 WEB Voices

After the destruction of the cities of the plain, Abraham sojourns in Gerar and again presents Sarah as his sister. Abimelech takes her; God warns the king in a dream, restrains him from sin, and restores Sarah through Abraham’s prophetic prayer—promise threatened, then preserved by the LORD.

Genesis 20:1

1Abraham traveled from there toward the land of the South, and lived between Kadesh and Shur. He lived as a foreigner in Gerar.

Arminian

Abraham moves south and sojourns in Gerar—still a guest, still on the road of promise. Location changes; vocation does not.

Classical Arminians notice a choice of place under God’s care. Grace accompanies the wanderer, yet the next verse will show how fear can still script the stay.

Reformed

“From there” continues providence after judgment on the cities. The patriarch’s sojourn is not random; Gerar becomes the next stage of the promise’s testing.

God shepherds Abraham even into foreign courts. The field of the next crisis is appointed, not accidental.

Genesis 20:2

2Abraham said about Sarah his wife, “She is my sister.” Abimelech king of Gerar sent, and took Sarah.

Arminian

The old Egypt tactic returns: “She is my sister.” Sarah is taken. Half-truth still endangers the wife of promise.

This is culpable unbelief, not clever diplomacy. Grace had already rescued them in chapter 12; repeating the scheme is a responsible failure, not fate.

Reformed

Abraham speaks; the king takes. The promise-line is immediately at risk in a pagan court.

Election does not make the patriarch flawless. God will have to keep Sarah, because Abraham’s word has put her—and the seed—in jeopardy.

Key contrast Both refuse to baptize the lie. Arminians stress Abraham’s resistible, repeated unbelief under a still-sincere promise; Calvinists stress that the same failure cannot void God’s purpose to preserve the line.

Genesis 20:3

3But God came to Abimelech in a dream of the night, and said to him, “Behold, you are a dead man, because of the woman whom you have taken; for she is a man’s wife.”

Arminian

God, not Abraham, protects Sarah. A night dream tells a Gentile king he is a dead man because he has taken another man’s wife.

Revelation reaches Abimelech so he may turn. The warning is severe and sincere—life is offered on the far side of obedience.

Reformed

Initiative is God’s: He comes, He names the crime, He announces death. Sarah is “a man’s wife” under divine witness.

The promise does not sleep in Gerar. God interrupts the king before the damage becomes irreversible.

Genesis 20:4

4Now Abimelech had not come near her. He said, “Lord, will you kill even a righteous nation?

Arminian

The narrator clears Abimelech of consummation. He pleads, “Lord, will you kill even a righteous nation? Didn’t?”—echoing Abraham’s own intercession for a city.

Arminians catch a Gentile appealing to God’s justice. Integrity matters; God is not arbitrary, and the king’s protest assumes a moral Lord who can be addressed.

Reformed

Restraint is already a fact: he had not approached her. His plea for an innocent people still comes under the God who has spoken death.

Even a pagan king knows to argue innocence before the LORD. Providence has kept the household from a sin not yet completed.

Genesis 20:5

5Didn’t he tell me, ‘She is my sister’? She, even she herself, said, ‘He is my brother.’ I have done this in the integrity of my heart and the innocence of my hands.”

Arminian

Abimelech cites both spouses’ words and claims integrity of heart and innocent hands. He was deceived into the taking.

Words have public consequence. Abraham and Sarah’s collusion placed a neighbor in moral danger; responsibility for the lie is not erased by the king’s sincerity.

Reformed

The king’s defense is twofold: he was told a lie, and his own heart was not predatory. Genesis lets that claim stand to be answered by God in the next verse.

God will vindicate the king’s integrity without excusing Abraham. Truth-telling in Gerar still belongs to the Lord of the promise.

Genesis 20:6

6God said to him in the dream, “Yes, I know that in the integrity of your heart you have done this, and I also withheld you from sinning against me. Therefore I didn’t allow you to touch her.

Arminian

God agrees: the king’s heart was integral. Then He adds the deeper mercy—“I also withheld you from sinning against me.” Touch was restrained.

Arminians hear both integrity and preventing grace. God can check a path before it becomes adultery; the king is still called to obey the word that follows.

Reformed

Divine knowledge and divine restraint meet. Integrity is granted, yet sin against God is averted because God did not let him touch her.

Preservation of the promise is God’s act. Abimelech’s clean hands are themselves a gift of providence, not autonomous luck.

Key contrast Both credit God with keeping Abimelech from touching Sarah. Arminians typically describe preventing grace that still leaves the king an obedient respondent; Reformed commentators emphasize sovereign restraint that effectually guards the covenant wife.

Genesis 20:7

7Now therefore, restore the man’s wife. For he is a prophet, and he will pray for you, and you will live. If you don’t restore her, know for sure that you will die, you, and all who are yours.”

Arminian

Return her: Abraham is a prophet who must pray so the king may live. Refusal means death for household as well as king.

The command is true. Life is offered through restitution and intercession; the warning is not theater. Grace restores through means the king can actually take.

Reformed

Abraham, despite the lie, is named prophet. Prayer is appointed as the path of the king’s life; refusal is certain death.

God uses a flawed prophet as means of mercy. The outcome—life or death—rests on the word God has spoken over Gerar.

Key contrast Both take the life-or-death command seriously. Arminians emphasize Abimelech’s responsible return under sincere threat and offer; Reformed Christians typically emphasize God’s appointed means (prophet’s prayer) that will effect the king’s life.

Genesis 20:8

8Abimelech rose early in the morning, and called all his servants, and told all these things in their ear. The men were very scared.

Arminian

Early rising, full disclosure, shared fear. The dream becomes public policy in the household.

Holy fear can be a right first response to God’s warning. The court treats the word as true and urgent—an example Abraham’s own fear did not match.

Reformed

The king does not delay. Servants hear, and fear spreads as the proper echo of God’s night word.

God can create the fear of God in Gerar that Abraham assumed was absent. Providence already begins to reverse the patriarch’s misreading.

Genesis 20:9

9Then Abimelech called Abraham, and said to him, “What have you done to us? How have I sinned against you, that you have brought on me and on my kingdom a great sin? You have done deeds to me that ought not to be done!”

Arminian

The pagan king catechizes the patriarch: What have you done? You brought a great sin on us. Things that ought not to be done.

Classical Arminians let the rebuke stand. Moral law is not Israel’s private code; Abraham’s scheme harmed a neighbor and a kingdom, and he is rightly called to account.

Reformed

Abimelech’s questions expose the scandal: the man of promise has imported sin into Gerar. “Ought not” is natural-law speech under God’s prior warning.

Common grace and conscience can shame the elect. God uses a Gentile king to name the patriarch’s wrong.

Genesis 20:10

10Abimelech said to Abraham, “What did you see, that you have done this thing?”

Arminian

“What did you see?” presses motive. The king wants the perception that produced the lie.

Fear-based seeing distorts neighbors. Abraham must own what he thought he saw—and how that seeing failed love.

Reformed

The question is diagnostic: what sight drove the deed? Unbelief had a vision of Gerar that God is about to contradict.

Wrong seeing of a place can still serve God’s larger exposing of the heart.

Genesis 20:11

11Abraham said, “Because I thought, ‘Surely the fear of God is not in this place. They will kill me for my wife’s sake.’

Arminian

Abraham confesses a thought: no fear of God here, therefore murder for Sarah’s sake. He judged a whole people unseen.

Anxious unbelief slanders neighbors and withholds trust from the God who had already protected him in Egypt. The fear of God was in Gerar; it was thin in Abraham’s plan.

Reformed

The motive is stated: assumed atheism of the place, assumed death. The father of faith reasoned from fear, not from promise.

God has just displayed fear of God in Abimelech’s court. Providence unmasks the patriarch’s misjudgment without discarding him.

Key contrast Both name Abraham’s motive as fearful unbelief. Arminians underline the culpable, correctable misreading of Gerar; Reformed readers emphasize that God still keeps the promise while exposing the patriarch’s false sight.

Genesis 20:12

12Besides, she is indeed my sister, the daughter of my father, but not the daughter of my mother; and she became my wife.

Arminian

He adds a technical defense: she is a half-sister who became his wife. True kinship does not make the concealment righteous.

Selective facts can still deceive. Marriage was the relevant truth in Gerar; hiding it remains sin even if genealogy is accurate.

Reformed

The half-truth is admitted. Genesis records the kinship without endorsing the use Abraham made of it.

Legal precision cannot cover covenant infidelity. God had already called her “a man’s wife.”

Genesis 20:13

13When God caused me to wander from my father’s house, I said to her, ‘This is your kindness which you shall show to me. Everywhere that we go, say of me, “He is my brother.”’”

Arminian

He traces the tactic to the original call: a standing request that Sarah call him brother at every place. Fear was policy, not a one-off.

Those in Wesley’s line hear how a grace-begun pilgrimage can carry a habitual scheme. “Kindness” asked of Sarah was costly; the pattern needed repentance, not repetition.

Reformed

Even “God caused me to wander” is turned into rationale for a traveling lie. Divine calling is named; trust is not practiced.

The God who called Abraham out still has to rescue the policy Abraham packed for the road.

Genesis 20:14

14Abimelech took sheep and cattle, male servants and female servants, and gave them to Abraham, and restored Sarah, his wife, to him.

Arminian

Restitution is concrete: livestock, servants, and Sarah returned as wife. The king obeys the dream with open-handed repair.

Wrong can be unwound in history. Grace uses a Gentile’s restitution to put the marriage—and the promise—back in the open.

Reformed

Sarah comes home by the king’s gift and God’s prior command. Abimelech’s goods accompany the return.

God can enrich the patriarch even through the aftermath of his own sin—without calling the sin wisdom.

Genesis 20:15

15Abimelech said, “Behold, my land is before you. Dwell where it pleases you.”

Arminian

Land is offered freely: dwell where it pleases you. The feared killer becomes a host.

The place Abraham read as godless now practices generosity. Neighbor-love from Gerar rebukes the sojourner’s suspicion.

Reformed

Hospitality replaces hostility. The king’s land is placed at Abraham’s disposal under the God who warned him.

Providence turns a death-dream into dwelling rights. The promise of land is tasted even in a foreign grant.

Genesis 20:16

16To Sarah he said, “Behold, I have given your brother a thousand pieces of silver. Behold, it is for you a covering of the eyes to all that are with you. In front of all you are vindicated.”

Arminian

Abimelech addresses Sarah, names “your brother,” and gives silver as public covering—her innocence vindicated before all.

Sarah is not a silent prop. The king’s speech restores her honor in the community Abraham’s ruse had compromised.

Reformed

A thousand pieces of silver function as public vindication. Sarah’s name is cleared in the eyes of all.

God sees to the honor of the woman through whom the seed must come. Even the awkward “your brother” cannot hide that she is restored as wife.

Genesis 20:17

17Abraham prayed to God. So God healed Abimelech, his wife, and his female servants, and they bore children.

Arminian

The prophet prays; God heals the king, his wife, and female slaves so they bear children. Intercession is effective means, not empty rite.

Arminian readers see prayer as God’s appointed way of restoring what sin had closed. Abraham must serve the very household he endangered—grace repairing through a responsible act of petition.

Reformed

Prayer and healing are paired: Abraham asks, God heals, wombs open. The prophet’s office, announced in the dream, is now performed.

God is the healer. He uses the patriarch’s prayer as means while remaining the One who opens wombs.

Key contrast Both tie healing to Abraham’s prayer. Arminians typically emphasize appointed, responsible intercession God sincerely uses; Reformed readers stress God’s effectual healing through the means He ordained.

Genesis 20:18

18For the LORD had closed up tight all the wombs of the house of Abimelech, because of Sarah, Abraham’s wife.

Arminian

The closing of wombs is now explained: because of Sarah, Abraham’s wife. God had already been acting for her honor before the prayer.

The LORD defends marriage and promise in a foreign house. Fertility itself can become a sign—judgment first, then mercy when the wife is restored.

Reformed

The narrator names the LORD as the closer of wombs. “Because of Sarah, Abraham’s wife” is covenant logic, not caprice.

God guarded the matriarch at the level of life itself. The Lord who closes also heals—sovereign over Gerar’s future as over Abraham’s.

Key contrast Both see the closed wombs as the LORD’s defense of Sarah. Arminians emphasize moral, responsive dealings that invite restoration; Reformed readers underline God’s sovereign, covenant protection of the promised line.

Historic quotes

Voices from both camps

Classic comment on Abraham, Abimelech, and God restraining a king from sin, from both sides of the debate.

Arminian Notable voices

“And Abraham sojourned in Gerar—We are not told upon what occasion he removed, whether terrified by the destruction of Sodom, or, as some of the Jewish writers say, because he was grieved at Lot's incest with his daughters, and the reproach which the Canaanites cast upon him for his kinsman's sake. The king of Gerar sent and took her—To his house, in order to the taking of her to his bed.”
John Wesley · Explanatory Notes upon the Old Testament (on Gen 20:1)

Reformed Notable voices

“What Moses related respecting the destruction of Sodom, was a digression. He now returns to the continuation of his history, and proceeds to show what happened to Abraham; how he conducted himself, and how the Lord protected him; till the promised seed, the future source of the Church, should be born unto him. He also says, that Abraham came into the South country; not that he traveled beyond the limits of the inheritance given to him, but left his former abode, and went towards the South.”
