'Barley harvest' in the Bible

So Naomi came back from the land of Moab with her daughter-in-law Ruth the Moabitess. They arrived in Bethlehem at the beginning of the barley harvest.

and handed them over to the Gibeonites. They hanged them on the hill in the presence of the Lord; the seven of them died together. They were executed in the first days of the harvest at the beginning of the barley harvest.
