In Old Testament Israel the cornerstone of each building was the chief stone from which every single measurement of the entire building was made. The cornerstone itself must, of necessity, be perfectly formed with every corner and side at 90 degrees from all others. The stone hewers were called stone squarers. It had to be laid perfectly level on every side. Any deviation in the form or arrangement of the cornerstone would be reflected in the entire building.
