'Barley harvest' in the Bible

And Naomi returned; and Ruth, who was of Moab, her daughter-in-law, was with her, returning out of the fields of Moab. And they came to Bethlehem in the beginning of barley harvest.

And she kept close by the maidens of Boaz to glean until the end of barley harvest and of wheat harvest. And she lived with her mother-in-law.
