Jeremiah 52:20-21

52:20 The bronze of the items that King Solomon made for the Lord’s temple (including the two pillars, the large bronze basin called “The Sea,” the twelve bronze bulls under “The Sea,” and the movable stands) was too heavy to be weighed. 52:21 Each of the pillars was about 27 feet high, about 18 feet in circumference, three inches thick, and hollow.
