'Barley' in the Bible

“There is a little boy here who has five barley loaves and two fish; but what are these for so many people?”

So they gathered them up, and they filled twelve large baskets with pieces from the five barley loaves which were left over by those who had eaten.

And I heard something like a voice in the midst of the four living creatures saying, “A quart of wheat for a denarius (a day’s wages), and three quarts of barley for a denarius; and do not damage the oil and the wine.”
