'Base' in the Bible

and I will turn again the captivity of Egypt, and will cause them to return to the land of Pathros, into the land of their birth, and they shall there be a base kingdom.

And these are the measures of the altar in cubits: the cubit is a cubit and a hand breadth. The bottom was a cubit in height and the breadth a cubit, and its border on the edge thereof round about, one span: and this was the base of the altar.
