1 Samuel 27:5-7

5Then David said to Achish, “If I have found favor in your eyes, let a place be assigned to me in one of the country towns, that I may live there. Why should your servant live in the royal city with you?” 6So on that day Achish gave him Ziklag, and it has belonged to the kings of Judah ever since.

7David lived in Philistine territory a year and four months.
