Matthew 13:47-52 - The Parable Of The Dragnet
47 Again, the kingdom of the heavens is like a net that was cast into the sea, and gathered from every kind, 48 which, when it was full, after dragging to the shore, having sat down, they gathered the good into vessels, but they cast out the useless. 49 So it will be at the end of the age. The heavenly agents will come forth, and separate the bad from among the righteous, 50 and will cast them into the furnace of fire. There will be the weeping and the gnashing of teeth.
51 Jesus says to them, Have ye understood all these things? They say to him, Yes, Lord.
52 And he said to them, Because of this every scholar who has been instructed in the kingdom of the heavens is like a man, a house-ruler, who brings forth out of his treasure things new and old.
