'Reaper' in the Bible

“And it will be like the reaper gathering the standing grain,As his arm harvests the ears of grain;Yes, it will be like one gleaning ears of grainIn the [fertile] Valley of Rephaim.

Speak, “Thus says the Lord,‘The dead bodies of men will fall like dung on the open field,And like sheaves [of grain] behind the reaper,And no one will gather them.’”

“Behold, the days are coming,” says the Lord,“When the plowman shall overtake the one who gathers the harvest,And the one who treads the grapes [shall overtake] him who sows the seed [for the harvest continues until planting time];When the mountains will drip sweet wineAnd all the hills shall melt [that is, everything that was once barren will overflow with streams of blessing].
