1 Samuel 27:1-2

Darby Translation

27 And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul will despair of me to seek me any more within all the limits of Israel, and I shall escape out of his hand.

² And David arose and passed over, he and the six hundred men that were with him, to Achish, the son of Maoch, king of Gath.
