'This Cup' in the Bible

In like manner also the cup, after supper, saying, This cup is the new covenant [sealed] with my blood; this do, as often as you drink, in remembrance of me.

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

So that whoever eats this bread or drinks this cup of the Lord unworthily, is guilty of the body and blood of the Lord.
