'Harvester' in the Bible

This is what the Lord who rules over all said to me: "Those who remain in Israel will be like the grapes thoroughly gleaned from a vine. So go over them again, as though you were a grape harvester passing your hand over the branches one last time."

Speak! "This is what the LORD says: "The corpses of people will fall like dung on the surface of the field, and like a row of cut grain behind the harvester when there is no one to gather it."'"
