'Bread' in the Bible

And the people came to make David take food, while it was still day, but David with an oath said, May God's punishment be on me if I take a taste of bread or any other thing till the sun has gone down!

And he gave to every man and woman among all the people, among all the masses of Israel, a cake of bread and a measure of wine and a cake of dry grapes. Then all the people went away, every man to his house.

Then Jonadab said to him, Go to your bed, and let it seem that you are ill: and when your father comes to see you, say to him, Let my sister Tamar come and give me bread, and get the food ready before my eyes, so that I may see it and take it from her hand.

And when David had gone a little way past the top of the slope, Ziba, the servant of Mephibosheth, came to him, with two asses on which were two hundred cakes of bread and a hundred stems of dry grapes and a hundred summer fruits and a skin of wine.

And David said to Ziba, What is your reason for this? And Ziba said, The asses are for the use of the king's people, and the bread and the fruit are food for the young men; and the wine is for drink for those who are overcome by weariness in the waste land.
