'Cup' in the Bible

The cup of blessing which we take, does it not give us a part in the blood of Christ? and is not the broken bread a taking part in the body of Christ?

It is not possible for you, at the same time, to take the cup of the Lord and the cup of evil spirits; you may not take part in the table of the Lord and the table of evil spirits.

In the same way, with the cup, after the meal, he said, This cup is the new testament in my blood: do this, whenever you take it, in memory of me.

For whenever you take the bread and the cup you give witness to the Lord's death till he comes.

If, then, anyone takes the bread or the cup of the Lord in the wrong spirit, he will be responsible for the body and blood of the Lord.

But let no man take of the bread and the cup without testing himself.
