Charles Ellicott Commentary 2 Chronicles 32:12

"Hath not the same Hezekiah taken away his high places and his altars, and commanded Judah and Jerusalem, saying, Ye shall worship before one altar, and upon it shall ye burn incense?" — 2 Chronicles 32:12 (ASV)

The same Hezekiah. — Hezekiah himself.

Ye shall worship ... upon it. —Literally, before one altar shall you worship, and on it shall you burn incense. Compare to 2 Kings 18:22: Is it not He whose high places and altars Hezekiah hath taken away, and commanded Judah and Jerusalem, Before this altar shall ye worship in Jerusalem? The chronicler is even more emphatic than Kings in asserting the sole validity of the Brazen Altar in the Temple Court.
