'Round' in the Bible

He made the molten sea of ten cubits from brim to brim, round in compass, and its height was five cubits; and a line of thirty cubits encircled it.

The mouth of it within the capital and above was a cubit: and its mouth was round after the work of a pedestal, a cubit and a half; and also on its mouth were engravings, and their panels were foursquare, not round.

In the top of the base was there a round compass half a cubit high; and on the top of the base its stays and its panels were of the same.

There were six steps to the throne, and the top of the throne was round behind; and there were stays on either side by the place of the seat, and two lions standing beside the stays.
