1st Samuel 27:4

1 And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should escape into the land of the Philistines; and Saul will despair of me, to seek me any more in all the borders of Israel: so shall I escape out of his hand.

2 And David arose, and passed over, he and the six hundred men that were with him, unto Achish the son of Maoch, king of Gath.

3 And 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.

4 And it was told Saul that David was fled to Gath: and he sought no more again for him.

5 And David said unto Achish, If now I have found favor in thine eyes, let them give me a place in one of the cities in the country, that I may dwell there: for why should thy servant dwell in the royal city with thee?

6 Then Achish gave him Ziklag that day: wherefore Ziklag pertaineth unto the kings of Judah unto this day.

7 And the number of the days that David dwelt in the country of the Philistines was a full year and four months.
