'Four square' in the Bible

"You shall make the altar of acacia wood, five cubits long, and five cubits broad; the altar shall be foursquare: and its height shall be three cubits.

The mouth of it within the capital and above was a cubit: and its mouth was round after the work of a pedestal, a cubit and a half; and also on its mouth were engravings, and their panels were foursquare, not round.

He measured the court, one hundred cubits long, and a hundred cubits broad, foursquare; and the altar was before the house.

All the offering shall be twenty-five thousand by twenty-five thousand: you shall offer the holy offering foursquare, with the possession of the city.

The city lies foursquare, and its length is as great as its breadth. He measured the city with the reed, Twelve thousand twelve stadia. Its length, breadth, and height are equal.
