'Barley' in the Bible

So Naomi returned, and with her Ruth the Moabitess, her daughter-in-law, who returned from the land of Moab. And they came to Bethlehem at the beginning of barley harvest.

So she gleaned in the field until evening. Then she beat out what she had gleaned, and it was about an ephah of barley.

So she stayed close by the maids of Boaz in order to glean until the end of the barley harvest and the wheat harvest. And she lived with her mother-in-law.

Now is not Boaz our kinsman, with whose maids you were? Behold, he winnows barley at the threshing floor tonight.

Again he said, “Give me the cloak that is on you and hold it.” So she held it, and he measured six measures of barley and laid it on her. Then she went into the city.

She said, “These six measures of barley he gave to me, for he said, ‘Do not go to your mother-in-law empty-handed.’”
