Caphtorims, a people akin to the Philistines, Genesis 10:14, and confederate with them in this enterprise, and so dwelling together, and by degrees were probably united together by marriages or other ways, and became one people, the Caphtorims being at last swallowed up in the Philistines. See Jeremiah 47:4 Amos 9:7. Caphtor is by the learned thought to be Cappadocia; whither these people might make an expedition out of Egypt, either because of the report of the great riches of part of that country, which drew others thither from places equally remote, or after the manner of those ancient times, or for some other reason now unknown.
