'Cup of' in the Bible

And whosoever shall give to one of these mean persons but a cup of cold water to drink, as my disciple, I assure you, he shall not lose his reward.

For whosoever shall give you but a cup of water to drink, for my sake; because ye are Christ's, I assure you, he shall not lose his reward.

---The cup of blessing which we bless, is it not the communion of the blood of Christ? the bread which we break, is it not the communion of the body of Christ?

And I would not have you partakers with demons. Ye cannot drink of the cup of the Lord, and the cup of demons: ye cannot be partakers of the table of the Lord, and of the table of demons.

So that whosoever eateth this bread, or drinketh of the cup of the Lord unworthily, shall be guilty of profaning the body and blood of the Lord.

or on his hand, he also shall drink of the wine of God's indignation poured forth without mixture, in the cup of his wrath; and 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 the cities of the nations fell: and great Babylon came into remembrance before God, to give her the cup of the wine of his fierce wrath.
