1 Samuel 27:2-4

So David left; he and his six hundred men went to Achish son of Maoch, king of Gath. They moved in and settled down in Gath, with Achish. Each man brought his household; David brought his two wives, Ahinoam of Jezreel and Abigail, widow of Nabal of Carmel. When Saul was told that David had escaped to Gath, he called off the hunt.
