1 Samuel 27:1-7

But David kept thinking to himself, “Someday Saul is going to get me. The best thing I can do is escape to the Philistines. Then Saul will stop hunting for me in Israelite territory, and I will finally be safe.” So David took his 600 men and went over and joined Achish son of Maoch, the king of Gath. David and his men and their families settled there with Achish at Gath. David brought his two wives along with him—Ahinoam from Jezreel and Abigail, Nabal’s widow from Carmel. Word soon reached Saul that David had fled to Gath, so he stopped hunting for him. One day David said to Achish, “If it is all right with you, we would rather live in one of the country towns instead of here in the royal city.” So Achish gave him the town of Ziklag (which still belongs to the kings of Judah to this day), and they lived there among the Philistines for a year and four months.
