17. Cut off. Ahaz probably needed the bronze as a present for the king of Assyria ( 18). He was obviously hard pressed and forced to secure metal wherever he could.
Borders of the bases. These “bases” were the stands for the ten brazen lavers built by Solomon (1 Kings 7:27-39). The borders were probably ornamental panelings. The bases themselves were not destroyed, for when Jerusalem was taken by Nebuchadnezzar these were among the items taken to Babylon (2 Kings 25:13, 16; Jer. 52:17, 20).
The sea. See 1 Kings 7:23-26. The great bronze laver itself was not destroyed, but was simply removed from the brazen oxen upon which it rested. When Jerusalem fell, this laver was broken up and taken to Babylon (Jer. 52:17) as a part of the booty.
