1 Samuel 27:1-7

But David said in his heart, “Now I will die one day by the hand of Saul. There is nothing better for me than to escape to the land of the Philistines. Then Saul will give up searching for me inside the borders of Israel, and I will escape from his hand [once and for all].” So David and the six hundred men who were with him arose and crossed over to Achish the son of Maoch, king of Gath. And David lived 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, [who was] Nabal’s widow. When Saul was told that David had fled to Gath, he no longer searched for him. Then David said to Achish, “If I have found favor in your sight, let me be given a place [of my own] in one of the cities in the country, so that I may live there; for why should your servant live in the royal city with you?” Then Achish gave David [the town of] Ziklag that day. Therefore Ziklag has belonged to the kings of Judah to this day. The number of days that David lived in the country of the Philistines was a year and four months.
