King Ahaz cut off the side panels and removed the basins from the movable stands. He removed the Sea from the bronze bulls that supported it and set it on a stone base. (NIV)
[To keep Assyria's king from getting them] King Ahaz cut off the panels of the bases [of the ten lavers] and removed the laver from each of them; and he took down the Sea from off the bronze oxen that were under it and put it upon stone supports. (AMP)
And king Ahaz cut off the borders of the bases, and removed the laver from off them; and took down the sea from off the brasen oxen that were under it, and put it upon the pavement of stones. (KJV)
