'Four square' in the Bible

And thou shalt make the altar of acacia wood, five cubits long, and five cubits broad; the altar shall be foursquare: and the height thereof shall be three cubits.

Foursquare it shall be and double; a span shall be the length thereof, and a span the breadth thereof.

A cubit shall be the length thereof, and a cubit the breadth thereof; foursquare shall it be; and two cubits shall be the height thereof: the horns thereof shall be of one piece with it.

And he made the altar of incense of acacia wood: a cubit was the length thereof, and a cubit the breadth thereof, foursquare; and two cubits was the height thereof; the horns thereof were of one piece with it.

And he made the altar of burnt-offering of acacia wood: five cubits was the length thereof, and five cubits the breadth thereof, foursquare; and three cubits the height thereof.

It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being double.
