'Bread' in the Bible

Let us then keep the feast, not with old leaven, and not with the leaven of evil thoughts and acts, but with the unleavened bread of true thoughts and right feelings.

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?

Because we, being a number of persons, are one bread, we are one body: for we all take part in the one bread.

For it was handed down to me from the Lord, as I gave it to you, that the Lord Jesus, on the night when Judas was false to him, took bread,

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.
