John Gill's Bible Commentary Ver. 4. And it was told Saul that David was fled to Gath , etc.] Who very probably had his spies out to watch his motions, and report to him where he was, and what he was doing: and he sought no more again for him ; by which it seems as if he would have sought after him again, had he continued in the land of Israel; but now being gone, and in an enemy’s country, and having nothing to fear from him while there, he laid aside all thoughts of seeking after him.
Matthew Henry Commentary
Verses 1-7 - Unbelief is a sin that easily besets even good men, when without ar fightings, and within are fears; and it is a hard matter to get ove 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 tha 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 comfortabl settlement, not only at a distance from Gath, but bordering upo Israel, where he might keep up a correspondence with his ow countrymen.
