1 Samuel 29:9

So they sent and gathered all the lords of the Philistines to them and said, “What shall we do with the ark of the God of Israel?” And they said, “Let the ark of the God of Israel be brought around to Gath.” And they brought the ark of the God of Israel around.

“Then your servant-woman said, ‘Please let the word of my lord the king be a resting place, for as the angel of God, so is my lord the king to listen with discernment through the good and evil. And may Yahweh your God be with you.’”

Now from Manasseh also some defected to David when he was about to go to battle with the Philistines against Saul. But they did not help them, for the lords of the Philistines after counsel sent him away, saying, “At the cost of our heads he may defect to his master Saul.”
