And he made the molten sea of ten cubits from brim to brim, round in compass, and the height thereof was five cubits; and a line of thirty cubits did compass it round about. And under the brim of it round about there were knops which did compass it, for ten cubits, compassing the sea round about; the knops were in two rows, cast when it was cast. It stood upon twelve oxen, three looking toward the north, and three looking toward the west, and three looking toward the south, and three looking toward the east; and the sea was set upon them above, and all their hinder parts were inward. And it was a hand-breadth thick; and the brim thereof was wrought like the brim of a cup, like the flower of a lily; it held two thousand baths.
I Kings 7:23-26
