'Reservoir' in the Bible

Now the Chaldeans broke into pieces the bronze pillars for the Lord’s temple and the water carts and the bronze reservoir that were in the Lord’s temple, and carried all the bronze to Babylon.

As for the two pillars, the one reservoir, and the 12 bronze bulls under the water carts that King Solomon had made for the Lord’s temple, the weight of the bronze of all these articles was beyond measure.
