Matthew 21:42

Jesus saith unto them, Did ye never read in the scriptures, The stone which the (u) builders rejected, the same is (x) become the (y) head of the corner: (z) this is the Lord's doing, and it is marvellous in our eyes?

(u) Master builders, who are chief builders of the house, that is of the Church.

(x) Began to be.

(y) The chiefest stone in the corner is called the head of the corner: which bears up the couplings or joints of the whole building.

(z) That matter (in that the stone which was cast away is made the head) is the Lord's doing which we behold and greatly marvel at.
