1 Samuel 27:2-7

2And David arose, and he passed over with the six hundred men that were with him to Achish, the son of Maoch, king of Gath. 3And David dwelt with Achish at Gath, he and his men, every man with his household, even David with his two wives, Ahinoam the Jezreelitess, and Abigail the Carmelitess, Nabal’s wife. 4And it was told to Saul that David had fled to Gath: and he sought no more again for him. 5And David said to Achish, If I have now found grace in thy eyes, let them give me a place in some town in the country, that I may dwell there: for why should thy servant dwell in the royal city with thee? 6Then Achish gave him Ziklag that day: therefore Ziklag pertaineth to the kings of Judah to this day. 7And the time that David dwelt in the country of the Philistines was a full year and four months.12
