'Four square' in the Bible

And in like manner, unto the door of the temple, he made posts of olive tree four square,

And he built the house of the wood of Lebanon, a hundred cubits long and fifty broad, and thirty high, four square with rows of Cedar pillars and Cedar beams along upon the pillars.

And all the doors with the side posts were four square one against another three fold.

And the mouth of it within the chapiter and above was a cubit: but the mouth thereof was round after the work of the base, a cubit and an half: and also upon the mouth of it were gravings with their borders, foursquare, not round.
