Strong, dependable. John’s vision of the New Jerusalem, the City of God. Truly translated, the city is square however the reference is equivalent to the nature of robustness and steady. “And the city lieth foursquare and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal.” Revelation 21:16 KJV
