"Then He took the cup, and gave thanks, and gave it to them, saying, “Drink from it, all of you. For this is My blood of the new covenant, which is shed for many for the remission of sins. 29 But I say to you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in My Father’s kingdom.”- Matthew 26:27-29
