Mark 14:24

So Moses took the blood and sprinkled it on the people and said, “Behold the blood of the covenant, which Yahweh has cut with you in accordance with all these words.”

And in the same way He took the cup after they had eaten, saying, “This cup which is poured out for you is the new covenant in My blood.

When Jesus had said these things, He became troubled in spirit, and bore witness and said, “Truly, truly, I say to you, that one of you will betray Me.”

The disciples began looking at one another, perplexed about whom He *spoke.

Is not the cup of blessing which we bless a sharing in the blood of Christ? Is not the bread which we break a sharing in the body of Christ?
