'Barley harvest' in the Bible

And the time when Naomi with Ruth the Moabitess, her daughter-in-law, returned out of the country of Moab and came to Bethlehem was in the beginning of barley harvest.

And so she kept her by the maidens of Boaz, to gather unto the end of barley harvest and of wheat harvest also: and dwelt with her mother-in-law.
