'Barley' in the Bible

So Naomi returned, and Ruth the Moabitess, her daughter in law, with her, which returned out of the country of Moab: and they came to Bethlehem in the beginning of barley harvest.

So she gleaned in the field until even, and beat out that she had gleaned: and it was about an ephah of barley.

So she kept fast by the maidens of Boaz to glean unto the end of barley harvest and of wheat harvest; and dwelt with her mother in law.

And now is not Boaz of our kindred, with whose maidens thou wast? Behold, he winnoweth barley to night in the threshingfloor.

Also he said, Bring the vail that thou hast upon thee, and hold it. And when she held it, he measured six measures of barley, and laid it on her: and she went into the city.

And she said, These six measures of barley gave he me; for he said to me, Go not empty unto thy mother in law.
