Another parable set he before them, saying, The kingdom of heaven is likened unto a man that sowed good seed in his field: but while men slept, his enemy came and sowed tares also among the wheat, and went away. But when the blade sprang up and brought forth fruit, then appeared the tares also. read more.
And the servants of the householder came and said unto him, Sir, didst thou not sow good seed in thy field? whence then hath it tares? And he said unto them, An enemy hath done this. And the servants say unto him, Wilt thou then that we go and gather them up? But he saith, Nay; lest haply while ye gather up the tares, ye root up the wheat with them. Let both grow together until the harvest: and in the time of the harvest I will say to the reapers, Gather up first the tares, and bind them in bundles to burn them; but gather the wheat into my barn.

Then he left the multitudes, and went into the house: and his disciples came unto him, saying, Explain unto us the parable of the tares of the field. And he answered and said, He that soweth 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; and the tares are the sons of the evil one ; read more.
and the enemy that sowed them is the devil: and the harvest is the end of the world; and the reapers are angels. As therefore the tares are gathered up and burned with fire; so shall it be in the end of the world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that cause stumbling, and them that do iniquity, and shall cast them into the furnace of fire: there shall be the weeping and the gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father. He that hath ears, let him hear.
