Charles Ellicott Commentary Zephaniah 2:5

"Woe unto the inhabitants of the sea-coast, the nation of the Cherethites! The word of Jehovah is against you, O Canaan, the land of the Philistines; I will destroy thee, that there shall be no inhabitant." — Zephaniah 2:5 (ASV)

The Cherethites. —Perhaps Cretans. See 1 Samuel 30:14; Ezekiel 25:16, where the same term is applied to the Philistines.

Canaan originally means “low-lying ground.” It here indicates the low maritime plain inhabited by the Philistines.
