It happened that a countryman was sowing some hemp1 seeds in afield where a swallow and some other birds were hopping2 aboutpicking up their food. "Beware of that man," Quoth the swallow. "Why, what is he doing?" Said the others. "That is hemp seed heis sowing; be careful to pick up every one of the seeds, or elseyou will repent3 it." The birds paid no heed4 to the swallow'swords, and by and by the hemp grew up and was made into cord, andof the cords nets were made, and many a bird that had despised theswallow's advice was caught in nets made out of that very hemp. "What did I tell you?" Said the swallow. 
Destroy the seed of evil, or it will grow up to your ruin.
