'Barley' in the Bible

"There's a little boy here who has five barley loaves and two small fish. But what are these among so many people?"

So they collected and filled twelve baskets full of pieces of the five barley loaves left over by those who had eaten.

I heard what sounded like a voice from among the four living creatures, saying, "One day's ration of wheat for a day's wage, or three day's ration of barley for a day's wage! But don't damage the olive oil or the wine!"
