'Circumference' in the Bible

He cast the two pillars of bronze; the one pillar was eighteen cubits high, and a [measuring] line of twelve cubits measured the circumference of both.

Now he made the Sea (basin) of cast metal, ten cubits from brim to brim, circular in form, five cubits high and thirty cubits in circumference.

Concerning the pillars, the height of each pillar was eighteen cubits (twenty-seven feet), and a line [an ornamental molding] of twelve cubits (eighteen feet) went around its circumference; it was four fingers thick, and [the pillar was] hollow.

So Jonah went to Nineveh in accordance with the word of the Lord. Now Nineveh was an exceedingly great city, a three days’ walk [about sixty miles in circumference].
