John Gill's Exposition of the Whole Bible
Jeremiah 52:17
Also the pillars of brass that [were] in the house of the Lord,.... The two pillars in the temple, called Jachin and Boaz, which were made of cast brass, 1 Kings 7:15;
and the bases; which were in number ten, and which were also made of cast brass, and were all of one measure and size; and on which the ten lavers of brass were set, five on the right side and five on the left side of the house, 1 Kings 7:37;
and the brasen sea that [was] in the house of the Lord; called the molten sea; a sea, because of the large quantity of water it held; and brasen and molten, because made of molten brass, 1 Kings 7:23;
the Chaldeans broke, and carried all the brass of them to Babylon: they broke them to pieces, that they might carry them the more easily. This account is given, and which is continued in some following verses, partly to show the accomplishment of the prophecy of Jeremiah,
Jeremiah 27:19; and partly to show that what was left in the temple, at the former captivities of Jehoiakim and Jeconiah, were now carried clear off.
