Matthew 13:47-52 - The Parable Of The Dragnet
47 Again, the gospel-kingdom is like a net that is cast into the sea, and draws all sorts of fish: 48 when it is full, they drag it to shore, then sit down, and pick out the good to lay by, but throw the bad away. 49 so it shall be at the end of the world: the angels shall come forth, and after they have separated the wicked from the just, 50 they shall cast the wicked into the furnace of fire: there shall be wailing and gnashing of teeth.
51 Then Jesus said to them, have ye understood all this?
52 they reply'd, yes, Lord. then said he to them, thus every teacher who is instructed in the doctrine of the gospel, is like the master of a family, who taketh out of his treasure things new and old.
