'Harvest time' in the Bible

Three of the thirty chief men went down, and came to David in the harvest time to the cave of Adullam; and the troop of the Philistines was encamped in the valley of Rephaim.

Let both grow together until the harvest, and in the harvest time I will tell the reapers, "First, gather up the darnel weeds, and bind them in bundles to burn them; but gather the wheat into my barn."'"
