Cornerstones

The cornerstone is another important part of the mason's work of which Scripture speaks. When the first layer of oblong stones is laid on the foundation, a broad square stone is selected for each corner where two walls meet. A thinner square block is usually put at each corner of the top rows of stones where the roof-beams are to rest. When trimming the oblong stones forming the bulk of the walls, it is easy for the mason to pass by the stone suitable for the cornerstone because of its uninviting shape. Thus the Psalmist said: "The stone which the builders refused is become the head stone of the corner" (Psalm 118:22). [Manners And Customs of Bible Lands]
