'Circular' in the Bible

Hiram also made a sea of cast metal ten cubits from brim to brim, circular in shape and five cubits and 30 cubits in its inner circumference.

On top of each stand was a circular structure one half of one cubit high, with its braces and support frames integral with it, forming a single piece.

He crafted a circular sea of cast metal 10 cubits from rim to rim and five cubits tall. A line 30 cubits long surrounded it.

Underneath, figurines resembling oxen encircled the circular sea beneath it, ten oxen every cubit, and encircling the sea completely. The oxen were in two rows, cast all at the same time.
