Jesus put before them another parable: “The kingdom of heaven is like a man who sowed good seed in his field. But while everyone was asleep, his enemy came and sowed weeds among the wheat, and slipped away. When the wheat sprouted and bore grain, then the weeds also appeared. The owner’s servants came to him and said, ‘Sir, didn’t you sow good seed in your field? Where then did the weeds come from?’ An enemy did this,’ he replied. So the servants asked him, ‘Do you want us to go and pull them up? No,’ he said, ‘if you pull the weeds now, you might uproot the wheat with them. Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and tie them in bundles to be burned; then gather the wheat into my barn... (Matthew 13:24-30)
