2 Chronicles 4:1-3

Then he made a bronze altar, twenty cubits in length, twenty cubits in width, and ten cubits in height.

He also made the Sea of cast metal, ten cubits from brim to brim, circular in form, and its height was five cubits and its circumference thirty cubits.

Now figures like oxen were under it and all around it, ten cubits, entirely encircling the Sea. The oxen were in two rows, cast in one piece.
