He put before them another parable, saying, "The kingdom of heaven may be compared to a man who sowed good seed in his field. But while his people were sleeping, his enemy came and sowed darnel in the midst of the wheat and went away. So when the {wheat} sprouted and yielded grain, then the darnel appeared also. read more.
So the slaves of the master of the house came [and] said to him, 'Master, did you not sow good seed in your field? How then does it have darnel?' And he said to them, 'An enemy has done this!' So the slaves said to him, 'Then do you want us to go [and] gather them?' But he said, "No, lest [when you] gather the darnel you uproot the wheat together with it. Let both grow together until the harvest, and at the season of the harvest I will tell the reapers, "First gather the darnel and tie it into bundles to burn them, but gather the wheat into my storehouse." '"

Then he left the crowds [and] came into the house, and his disciples came to him saying, "Explain the parable of the darnel in the field to us." So he answered [and] said, "The one who sows the good seed is the Son of Man, and the field is the world. And the good seed--these are the sons of the kingdom, but the darnel are the sons of the evil one. read more.
And the enemy who sowed them is the devil, and the harvest is the end of the age, and the reapers are angels. Thus just as the darnel is gathered and burned with fire, so it will be at the end of the age. The Son of Man will send out his angels and they will gather out of his kingdom all the causes of sin and those who do lawless deeds, and throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth! Then the righteous will shine like the sun in the kingdom of their Father. The one who has ears, let him hear!
