Albert Barnes Commentary Zephaniah 2:6

"And the sea-coast shall be pastures, with cottages for shepherds and folds for flocks." — Zephaniah 2:6 (ASV)

The seacoast shall be dwellings and cottages - literally, cuttings or diggings. This is the central meaning of the word; the place of the Cherethites (the cutters off) shall be "cheroth" of shepherds, places which they dug up so that their flocks might be enclosed in them. The tracts once full of fighting men, the scourge of Judah, should be so desolate of its former people as to become a sheep-walk. Men of peace should take the place of its warriors.

So the shepherds of the Gospel with their flocks have entered into possession of warlike nations, turning them to the Gospel. They are shepherds, the chief of whom is that Good Shepherd, who laid down His Life for the sheep. And these are the sheep of whom He speaks, "Other sheep I have, which are not of this fold; them also I must bring, and they shall hear My Voice; and there shall be one fold and One Shepherd" (John 10:16).
