Psalms 17:1
1Hear, LORD, my righteous plea. Give ear to my prayer that doesn’t go out of deceitful lips.
Wesley: The right—Regard my righteous cause. David opens by appealing to God for integrity: a cry and prayer that do not go out of feigned lips.
Ask God to hear a just cause from honest lips. Grace enables sincere prayer; the hearer must still refuse deceit and bring a cause, not a covered sin, before the LORD.
Calvin: David sets forth the goodness of his cause because God has promised not to suffer the innocent to be forever oppressed. Confiding in integrity, he interposes God as Judge; yet adds earnest cry and prayer—hypocrites cover sins with loud piety, but he protests he does not speak deceitfully. The finest grace before God is pure simplicity.
Sincere prayer under a just cause. A good conscience alone is not enough; the cause must be committed to God in faith and prayer, not clenched in stubborn silence.
