This watercolor image by J. Tissot shows a man planting weed seed in his enemy's agricultural field at night. The artwork derives from one of the parables of Jesus Christ regarding what the kingdom of heaven is like.
"Another parable he proposed to them, saying: The kingdom of heaven is likened to a man that sowed good seeds in his field. But while men were asleep, his enemy came and oversowed cockle among the wheat and went his way. And when the blade was sprung up, and had brought forth fruit, then appeared also the cockle. And the servants of the goodman of the house coming said to him: Sir, didst thou not sow good seed in thy field? whence then hath it cockle? And he said to them: An enemy hath done this. And the servants said to him: Wilt thou that we go and gather it up? And he said: No, lest perhaps gathering up the cockle, you root up the wheat also together with it. Suffer both to grow until the harvest, and in the time of the harvest I will say to the reapers: Gather up first the cockle, and bind it into bundles to burn, but the wheat gather ye into my barn." — Matthew 13:24-30
