A young girl and ten of her maid-servants were once kidnapped, when a
certain Gentile bought them and brought them to his house. One day he
gave a pitcher to the child and bade her fetch him water, but one of her
servants took the pitcher from her, intending to go instead. The master,
observing this, asked the maid why she did so. The servant replied, "By
the life of thy head, my lord, I am one of no less than five hundred
servants of this child's mother." The master was so touched that he
granted them all their freedom.
