Matthew 13:48
When it became full, the fishermen dragged it up onto the shore. Then they sat down and, [sorting their catch], placed the good [i.e., edible fish] into containers, but threw out the bad [i.e., inedible ones].
Matthew 3:12
His winnowing shovel [Note: This was a process whereby grain was tossed into the air so that the wind could blow the husks away, leaving only good grain on the ground] is in His hand and He will completely clear off His threshing floor [by removing all of the husks]. And He will gather His wheat into the barn, but will burn up the husks with a fire that will never go out."
Matthew 13:30
Let both of them grow together until it is time for the harvest; then at that time, I will tell the harvesters, "Gather up the weeds first, and bind them up into bundles to burn. But gather the wheat into my barn."'"
Matthew 13:40-43
Just like the weeds were gathered up and burned with fire, so it will be at the end of the world.
