Charles Ellicott Commentary 2 Chronicles 25:23

"And Joash king of Israel took Amaziah king of Judah, the son of Joash the son of Jehoahaz, at Beth-shemesh, and brought him to Jerusalem, and brake down the wall of Jerusalem from the gate of Ephraim unto the corner gate, four hundred cubits." — 2 Chronicles 25:23 (ASV)

Jehoahaz. — Several Hebrew manuscripts read Ahaziah, as in 2 Kings 14:13, with which the rest of the verse agrees: see the Notes there. (See Note on 2 Chronicles 21:17.)

The corner gate. — So 2 Kings 14:13, rightly. Our Hebrew text has, “gate of the turning one,” or “gate that turns;” which would require some word indicating the direction of the turning. (Compare to Ezekiel 8:3, gate that turneth northward.) Some manuscripts, and all the versions, agree with Kings. It is merely a matter of different points. (Compare also to 2 Chronicles 26:9.)
