Jeremiah 52:21 In-Context

19 The commander of the guard took the cups, censers, sprinkling bowls, pots, menorahs, pans and bowls - everything made of gold and everything made of silver.

20 The bronze in the two columns, the one Sea, and the twelve bronze bulls under the bases, all of which Shlomo had made for the house of ADONAI, was more than could be weighed.

21 As for the columns, the height of one column was thirty-one-and-a-half feet; it took a twenty-one-foot measuring line to go around it; and its thickness was four fingers - it was hollow.

22 On it was a capital of brass eight-and-three quarters feet high, with netting and pomegranates all around the capital, all of bronze; the second column was similar, also with pomegranates.

23 There were ninety-six pomegranates on the outside; while the total number of pomegranates in the netting was one hundred.
