'Edge' in the Bible

And he maketh the molten sea; ten by the cubit, from its edge unto its edge, round in compass, and five by the cubit its height, and a line of thirty by the cubit doth compass it, round about.

It was as thick as a man's open hand, and the edge of it was curved like the edge of a cup, like a lily flower; it would take three thousand baths.

Then Solomon went to Ezion-Geber, and to Elath, on the edge of the sea in the land of Edom.
