1 Samuel 26:19

If the Lord have stirred thee up - The meaning is clear from the preceding history. “An evil spirit from God troubling him” was the beginning of the persecution. And this evil spirit was sent in punishment of Saul’s sin 1 Samuel 16:1, 1 Samuel 16:14. If the continued persecution was merely the consequence of this evil spirit continuing to vex Saul, David advises Saul to seek God’s pardon, and, as a consequence, the removal of the evil spirit, by offering a sacrifice. But if the persecution was the consequence of the false accusations of slanderers, then “cursed” be his enemies who, by their actions, drove David out from the only land where Yahweh was worshipped, and forced him to take refuge in the country of pagan and idolaters (compare Deuteronomy 4:27; Deuteronomy 28:36).
