'Bread' in the Bible

Therefore, let us observe the feast, not with old yeast or with the yeast of malice and evil but with the unleavened bread of sincerity and truth.

The cup of blessing that we give thanks for, is it not a sharing in the blood of Christ? The bread that we break, is it not a sharing in the body of Christ?

Because there is one bread, we who are many are one body, for all of us share that one bread.

For I received from the Lord what I also passed on to you: On the night when He was betrayed, the Lord Jesus took bread,

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

Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy way will be guilty of sin against the body and blood of the Lord.

So a man should examine himself; in this way he should eat the bread and drink from the cup.
