2 So David took his 600Â men and went over and joined Achish son of Maoch, the king of Gath. 3 David and his men and their families settled there with Achish at Gath. David brought his two wives along with him-Ahinoam from Jezreel and Abigail, Nabal's widow from Carmel. 4 Word soon reached Saul that David had fled to Gath, so he stopped hunting for him.

Commentary on 1 Samuel 27:1-7
(Read 1 Samuel 27:1-7)
Unbelief is a sin that easily besets even good men, when without are fightings, and within are fears; and it is a hard matter to get over them. Lord, increase our faith! We may blush to think that the word of a Philistine should go further than the word of an Israelite, and that the city of Gath should be a place of refuge for a good man, when the cities of Israel refuse him a safe abode. David gained a comfortable settlement, not only at a distance from Gath, but bordering upon Israel, where he might keep up a correspondence with his own countrymen.
