Nebuchadnezzar thereupon, that is to say, when he had forced his way into the city, plundered the treasures of the temple and palace, and broke the gold off the vessels which Solomon had made in the temple of Jehovah. קצּץ, to cut off, break off, as in Kg2 16:17, i.e., to bear off the gold plates. Nebuchadnezzar had already taken a portion of the golden vessels of the temple away with him at the first taking of Jerusalem in the fourth year of Jehoiakim, and had placed them in the temple of his god at Babylon (Ch2 36:7; Dan 1:2). They were no doubt the smaller vessels of solid gold-basins, scoops, goblets, knives, tongs, etc., - which Cyrus delivered up again to the Jews on their return to their native land (Ezr 1:7.). This time he took the gold off the larger vessels, which were simply plated with that metal, such as the altar of burnt-offering, the table of shew-bread and ark of the covenant, and carried it away as booty, so that on the third conquest of Jerusalem, in the time of Zedekiah, beside a few gold and silver basins and scoops (Kg2 25:15) there were only the large brazen vessels of the court remaining (Kg2 25:13-17; Jer 27:18.). The words, "as Jehovah had spoken," refer to Kg2 20:17 and Isa 39:6, and to the sayings of other prophets, such as Jer 15:13; Jer 17:3, etc.
