'Barley harvest' in the Bible

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

So she kept with the maidens of Boaz to glean, until the end of the barley-harvest and of the wheat-harvest. And she dwelt with her mother-in-law.

and he gave them into the hands of the Gibeonites, and they hanged them on the hill before Jehovah. And they fell all seven together, and were put to death in the first days of the harvest, in the beginning of barley harvest.
