This history is not recorded elsewhere in Scripture, but it is in the ancient Hebrew writers, though mixed with many fables. The Philistines (one of whose cities this Gath was) and the Egyptians were next neighbours; and in those ancient times it was usual for such to make inroads one into another's country, and to carry thence what prey they could take, as we find both in Scripture and in profane writers. And as the Philistines had probably made such inroads formerly into Egypt, and particularly into the land of Goshen, which was the utmost part of Egypt bordering upon the Philistines land; so the Israelites might requite them in the like kind: and particularly the children of Ephraim, either presuming upon their numbers and strength, or having possibly received the greatest injury from the Philistines in their last invasion, might make an attempt upon the Philistines to their own great loss, as is here related. And this seems to have happened a little before the Egyptian persecution, and before the reign of that new king mentioned Exodus 1:8. The Philistines are here called the men of Gath, either because they were subject to the king of Gath, as afterwards that people were, or because they lived about Gath. And this clause, that were born in that land, may be added emphatically, as the motive which made them more resolute and furious in their fight with the Ephraimites, because they fought in and for their own land, wherein all their wealth and concerns lay, and against those that unjustly endeavoured to turn them out of their native country.
