1 Samuel 27:2-4

2 So David and his 600 men went across the border of Israel to Gath town. Maoch's son Achish was the king there. 3 David and his men lived in Gath with King Achish. They had their families with them. David's two wives were with him: Ahinoam from Jezreel, and Abigail from Carmel. Abigail was Nabal's widow. 4 Saul heard the news that David had run away to Gath. So he stopped looking for David.
