'Barley harvest' in the Bible

So Naomi returned, accompanied by her Moabite daughter-in-law Ruth, who came back with her from the region of Moab. (Now they arrived in Bethlehem at the beginning of the barley harvest.)

So Ruth worked beside Boaz's female servants, gathering grain until the end of the barley harvest as well as the wheat harvest. After that she stayed home with her mother-in-law.
