'This Cup' in the Bible

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

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

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