'Barley' in the Bible

So Naomi returned, and Ruth the Moabitess, her daughter-in-law, with her, who 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 she beat out that which 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 she dwelt with her mother-in-law.

And now is not Boaz our kinsman, with whose maidens thou wast? Behold, he winnoweth barley to-night in the threshing-floor.

And he said, Bring the mantle that is upon thee, and hold it; and she held it; and he measured six measures of barley, and laid it on her: and he went into the city.

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