Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. Raise up seed unto his brother - This law is mentioned Deuteronomy 25:5. The meaning of the expression is, that the children produced by this marriage should be reckoned in the genealogy of the deceased brother, and enjoy his estates. The word seed should be always translated children or posterity. There is a law precisely similar to this among the Hindoos.
