2 Chronicles 4:1-2

Young's Literal Translation

4 And he maketh an altar of brass, twenty cubits its length, and twenty cubits its breadth, and ten cubits its height.

² 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.
