1 Corinthians 11:25

When he had supped] RV 'after supper.' The bread was taken and distributed by our Lord during the Passover feast: cp. Matthew 26:26 the cup was given at the close of the feast, and may have been the ordinary cup of thanksgiving taken at the conclusion of the Passover feast, set apart by Christ to this special purpose henceforth. This cup is the new testament (RV 'covenant') in my blood] So Lk, Mt, Mk, 'this is my blood of the covenant.' Christ's Blood establishes a new covenant between God and man, one of forgiveness and grace: cp. Hebrews 8:6; Hebrews 9:15. The cup is a seal or assurance of our being included within this covenant.
