1 Samuel 27:1-7

Then David said to himself, “Now I will perish one day by the hand of Saul. There is nothing better for me than to escape into the land of the Philistines. Saul then will despair of searching for me anymore in all the territory of Israel, and I will escape from his hand.” So David arose and crossed over, he and the six hundred men who were with him, to Achish the son of Maoch, king of Gath. And David lived with Achish at Gath, he and his men, each with his household, even David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal’s widow. Now it was told Saul that David had fled to Gath, so he no longer searched for him. Then David said to Achish, “If now I have found favor in your sight, let them give me a place in one of the cities in the country, that I may live there; for why should your servant live 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. The number of days that David lived in the country of the Philistines was a year and four months.
