'Barley harvest' 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, entered Bethlehem in the beginning of barley harvest.

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

and delivered them up into the hand of the Gibeonites, and they crucified them in the mountain, before Yahweh, so they seven fell together, - they being put to death in the first days of harvest, in the beginning of the barley harvest.
