1 Samuel 26:19
Now therefore, I pray thee, let my lord the king hear the words of his servant. If the LORD have stirred thee up against me, let him accept an offering: but if they be the children of men, cursed be they before the LORD; for they have driven me out this day from abiding in the inheritance of the LORD, saying, Go, serve other gods.
The verse belongs to the account of David's magnanimity after Abiathar escaped and fled to David when Saul slew the priests, at which time David promised Abiathar safety with him because Saul sought both their lives. It is spoken after David has spared Saul's life a second time, while David stands on the top of a hill at a safe distance from Saul's camp and points to the king's spear and cruse of water as proof of what he has done.
In the verse David asks the king to hear him about why he is pursued when he has done nothing and no evil is in his hand, and this appeal follows his rebuke of Abner for failing to guard the Lord's anointed. The appeal brings a deeper and more humble acknowledgment of fault from Saul, who confesses that he has sinned and acted foolishly, promises to do David no more harm, and blesses him. Even after that confession and blessing, David does not place himself in Saul's power because he has no hope that the king will long remain in that repentant frame of mind.
