So whosoever may eat the bread or drink the cup of the Lord unworthily, shall be guilty of the body and the blood of the Lord.

and he shall drink of the wine of the wrath of God, having been poured out without mixture in the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb.

And the great city was divided into three parts, and cities of the Gentiles fell. And great Babylon came into remembrance before God, to give unto her the cup of the wine of the wrath of his indignation.
