2 Chronicles 28:16

King James Version (KJV)

At that time did king Ahaz send unto the kings of Assyria to help him.

Adam Clarke
Bible Commentary

The kings of Assyria to help him - Instead of מלכי malchey ; Kings; the Vulgate, Syriac, Arabic, and Chaldee, one MS., and the parallel place, 2 Kings 16:7, have מלך melek, King, in the singular number. This king was Tiglath-pileser, as we learn from the second book of Kings.
