'Reapers' in the Bible

Then He said to His disciples, "The harvest is abundant, but the reapers are few;

therefore entreat the Owner of the Harvest to send out reapers into His fields."

Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.

The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.
