Jesus said to them, "Did you never read in the Scriptures:
The stone that the builders rejected
 has become the cornerstone;
 by the Lord has this been done,
 and it is wonderful in our eyes?
(Mt 21:33-43,45-46)

This passage from Psalm 118 (Ps 118:22-23) is so important to early Christian preaching and teaching about the Crucifixion and the Resurrection that it is cited also in two other passages of the New Testament, Acts 4:11 and I Peter 2:7. It forms an essential part of the liturgy of Easter Sunday.
