Commentary for Ezekiel 25:16

the Cherethites [Heb. כְּרֵתִים,] a nation deserving of being cut off (Targum). But I say, because I saw elsewhere that Scripture calls the Philistines כְּרֵתִים (Zeph. 2:5): “Woe to the inhabitants of the seacoast, the nation of (כְּרֵתִים),” and it does not give any other nation this appellation, it appears to me that there is a region of Philistia called Chereth, and so I find in the Book of (I) Samuel (30:14), concerning the group that set fire to Ziklag: “We made a raid on the south of the Cherethites.”

the seacoast [Heb. חוֹף הַיָם,] marche in Old French, frontier, borderland. They are Philistines, who live in the southwestern corner of the land of Israel on the Western (Mediterranean) Sea.
