1 Samuel 27:3

David had also taken Ahinoam of Jezreel, and they both became his wives.

Then the commanders of the Philistines said, “What are these Hebrews doing here?” And Achish said to the commanders of the Philistines, “Is this not David, the servant of Saul the king of Israel, who has been with me these days, or rather these years, and I have found no fault in him from the day he deserted to me to this day?”

Now these are the ones who came to David at Ziklag, while he was still restricted because of Saul the son of Kish; and they were among the mighty men who helped him in war.
