Psalms 51:1
1Have mercy on me, God, according to your loving kindness. According to the multitude of your tender mercies, blot out my transgressions.
Have mercy—according to steadfast love and abundant mercy blot out transgressions. Wesley heard lovingkindness and the multitude of tender mercies as the ground of the plea after Nathan exposed David. The king does not bargain; he begs blot-out.
Mercy is true and must be sought. Grace that can blot also summons confession. David’s aggravated sin does not undo the invitation to ask; it deepens the need for rich mercy received.
Calvin: David begins by praying for pardon with unwonted earnestness—ordinary kindness would not suffice for so great a sinner. He piles loving-kindness and multitude of compassions because the stain felt deep.
Pardon is God’s work according to His compassions, not David’s worth. The plea rests on who God is. Common confession: blot out is needed; neither camp softens Bathsheba’s aftermath.
Key contrast Both plead rich mercy to blot out. Arminians stress sincere petition that must still be made; Reformed commentators emphasize that only the multitude of God’s compassions can cover such guilt.
