Charles Ellicott Commentary 2 Kings 25:16

"The two pillars, the one sea, and the bases, which Solomon had made for the house of Jehovah, the brass of all these vessels was without weight." — 2 Kings 25:16 (ASV)

The two pillars, (the) one sea ... —A nominative absolute.

All these vessels ... —Those just mentioned, the two pillars, etc.

Without weight. —A natural hyperbole closely resembling one which we often find in Assyrian accounts of the plunder carried off from conquered towns: “spoils without number carried off.”
