'Barley bread' in the Bible
And Gideon cometh in, and lo, a man is recounting to his companion a dream, and saith, 'Lo, a dream I have dreamed, and lo, a cake of barley-bread is turning itself over into the camp of Midian, and it cometh in unto the tent, and smiteth it, and it falleth, and turneth it upwards, and the tent hath fallen.'
A man from Baal-shalishah came to the man of God with his sack full of 20 loaves of barley bread from the first bread of the harvest. Elisha said, “Give it to the people to eat.”
And they replied, "But we have here [only] five loaves of [barley] bread [See John 6:9] and two [probably smoked] fish."
But He said to the apostles, "You men give them something to eat." But they replied, "We have only five loaves of [barley] bread [See John 6:9] and two [probably smoked] fish, unless we go and buy [more] food for all these people."
"There is a little boy here who has five [small] loaves of barley bread and two [probably smoked] fish. But what is this amount for [feeding] so many people?"
So, they gathered them up and filled twelve baskets with broken pieces left over from the five loaves of barley bread which they had eaten.
