'Bread' in the Bible

Therefore let us keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.

The cup of blessing which we bless, isn't it a sharing of the blood of Christ? The bread which we break, isn't it a sharing of the body of Christ?

Because there is one loaf of bread, we, who are many, are one body; for we all partake of the one loaf of bread.

For I received from the Lord that which also I delivered to you, that the Lord Jesus on the night in which he was betrayed took bread.

For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes.

Therefore whoever eats this bread or drinks the Lord's cup in a way unworthy of the Lord will be guilty of the body and the blood of the Lord.

But let a man examine himself, and so let him eat of the bread, and drink of the cup.
