Charles Ellicott Commentary 2 Kings 18:16

"At that time did Hezekiah cut off [the gold from] the doors of the temple of Jehovah, and [from] the pillars which Hezekiah king of Judah had overlaid, and gave it to the king of Assyria." — 2 Kings 18:16 (ASV)

Cut off the gold from the doors. —Literally, trimmed, or stripped the doors (the word used in 2 Kings 16:17 of the similar proceeding of Ahaz). The leaves of the doors of the sanctuary were overlaid with gold (1 Kings 6:18; 1 Kings 6:32; 1 Kings 6:35). Hard necessity drove Hezekiah to strip off this gold, as well as that with which he had himself plated “the pillars” or rather the framework of the doors (literally, the supporters; others think that the door-posts only are meant by this term).
