'Encircled' in the Bible

For he fashioned the two pillars of brass, eighteen cubits high apiece: and a line of twelve cubits encircled either of them about.

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.

Under its brim around there were buds which encircled it, for ten cubits, encircling the sea: the buds were in two rows, cast when it was cast.
