Charles Ellicott Commentary 2 Chronicles 28:16

"At that time did king Ahaz send unto the kings of Assyria to help him." — 2 Chronicles 28:16 (ASV)

UNDER THE PRESSURE OF NEW ENEMIES, AHAZ ASKS HELP FROM ASSYRIA, BUT RECEIVES HURT (2 Chronicles 28:17–21). (Compare to 2 Kings 16:7–18.)

At that time. —Apparently after the events narrated above; how soon after we can hardly decide.

The kings of Assyria. —A generalised expression, as in 2 Chronicles 28:3 (compare to 2 Chronicles 28:20–21), where the actual king is named. All the old versions have “king.”
