'Four square' in the Bible

And thou shalt make an altar of sethim-wood: five cubits long and five cubits broad, that it be foursquare, and three cubits high.

Foursquare it shall be and double, a hand breadth long and a hand breadth broad.

a cubit long, and a cubit broad, even foursquare shall it be and two cubits, high: with horns proceeding out of it,

And he made the cense altar of sethim-wood of a cubit long and a cubit broad: even four square, and two cubits high with horns proceeding out of it.

And he made the burnt offering altar of sethim-wood, five cubits long and five cubits broad: even four square, and three cubits high.

And they made it four square and double, a hand breadth long and a hand breadth broad.
