'Barley harvest' in the Bible

So Naomi returned from the country of Moab, and with her Ruth the Moabitess, her daughter-in-law. And they arrived in Bethlehem at the beginning of the barley harvest.

He handed them over to the Gibeonites, and they hanged them on the hill before the Lord, and the seven died together. They were put to death in the first days of the grain harvest, the beginning of the barley harvest [in the spring].
