'Loaf' in the Bible

Or what man is there of you who, if his son shall ask of him a loaf of bread, will give him a stone;

And they forgot to take bread, and save one loaf, they had not any with them in the ship.

And having taken a loaf, when he had given thanks, he broke it, and gave it to them, saying, This is my body which is given for you: this do in remembrance of me.

And, having said these things and taken a loaf, he gave thanks to God before all, and having broken it began to eat.

Because we, being many, are one loaf, one body; for we all partake of that one loaf.
