1 Samuel 27:5 (KJV)

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.

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

And David said unto Achish, If I have now found grace in thine 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?

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

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