Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man who sowed good seed in his field: But while men slept, his enemy came and sowed tares among the wheat, and went his way. But when the plant was sprung up, and brought forth fruit, then appeared the tares also. So the servants of the householder came and said unto him, Sir, did you not sow good seed in your field? from where then has it tares? He said unto them, An enemy has done this. The servants said unto him, Will you then that we go and gather them up? But he said, Nay; lest while you gather up the tares, you root up also the wheat with them. Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather you together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn. (Matthew 13:24-30)
