'Bread' in the Bible

The cup of the blessing that we bless -- is it not the fellowship of the blood of the Christ? the bread that we break -- is it not the fellowship of the body of the Christ?

because one bread, one body, are we the many -- for we all of the one bread do partake.

For I -- I received from the Lord that which also I did deliver to you, that the Lord Jesus in the night in which he was delivered up, took bread,

for as often as ye may eat this bread, and this cup may drink, the death of the Lord ye do shew forth -- till he may come;

so that whoever may eat this bread or may drink the cup of the Lord unworthily, guilty he shall be of the body and blood of the Lord:

and let a man be proving himself, and so of the bread let him eat, and of the cup let him drink;
