I Samuel 27:1-7

And David said in his heart, “Now I shall perish someday by the hand of Saul. There is nothing better for me than that I should speedily escape to the land of the Philistines; and Saul will despair of me, to seek me anymore in any part of Israel. So I shall escape out of his hand.” Then David arose and went over with the six hundred men who were with him to Achish the son of Maoch, king of Gath. So David dwelt with Achish at Gath, he and his men, each man with his household, and David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal’s widow. And it was told Saul that David had fled to Gath; so he sought him no more. Then David said to Achish, “If I have now found favor in your eyes, let them give me a place in some town in the country, that I may dwell there. For why should your servant dwell in the royal city with you?” So Achish gave him Ziklag that day. Therefore Ziklag has belonged to the kings of Judah to this day. Now the time that David dwelt in the country of the Philistines was one full year and four months.
