'This Cup' in the Bible

After the same manner also he took the cup, after he had eaten, saying, This cup is the new testament in my blood: this do you, as often as you drink it, in remembrance of me.

For as often as you eat this bread, and drink this cup, you do show the Lord's death till he comes.

Therefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord.
