Charles Ellicott Commentary 2 Chronicles 28:1

"Ahaz was twenty years old when he began to reign; and he reigned sixteen years in Jerusalem: and he did not that which was right in the eyes of Jehovah, like David his father;" — 2 Chronicles 28:1 (ASV)

THE REIGN OF AHAZ. (Compare to 2 Kings 16)

PRELIMINARY NOTICES OF THE LENGTH AND CHARACTER OF THE REIGN (2 Chronicles 28:1–4).

Ahaz was twenty years old. — The verse is identical with 2 Kings 16:2; the Septuagint, Syriac, and Arabic read “twenty and five.” (See 2 Chronicles 29:1.)

The Lord. — Add his God. This reading is found in some manuscripts and the Syriac version; the Book of Kings also has this reading. The Assyrian monuments call Ahaz Yahuhazi, i.e., Jehoahaz, of which Ahaz may be a familiar abridgment. (Compare Nathan, Jonathan.)
