Charles Ellicott Commentary Zephaniah 1:4

"And I will stretch out my hand upon Judah, and upon all the inhabitants of Jerusalem; and I will cut off the remnant of Baal from this place, [and] the name of the Chemarim with the priests;" — Zephaniah 1:4 (ASV)

The remnant of Baal. — That is, Baal worship shall be completely and utterly abolished. Not even a remnant of it shall be left. The term “remnant” does not necessarily imply, as Kleinert argues, that a large part of Baal worship had already been overthrown by Josiah’s reformation.

The Chemarims. — In 2 Kings 23:5, this is the designation of the “idolatrous priests whom the kings of Judah had ordained to burn incense in the high places.” The term is used again in Hosea 10:5. Even the very name of these intruders is to be abolished.

The priests. — These are probably a certain section of the Jewish priesthood who had winked at this establishment of false worship.
