Context
19 The captain of the guard took away the cups, the fire pans, the basins, the pots, the lamp stands, the spoons, and the bowls; that which was of gold, as gold, and that which was of silver, as silver.
20 They took the two pillars, the one sea, and the twelve bronze bulls that were under the bases, which King Solomon had made for the LORD’s house. The bronze of all these vessels was without weight.
21 As for the pillars, the height of the one pillar was eighteen cubits; and a line of twelve cubits encircled it; and its thickness was four fingers. It was hollow.
