Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.
and they asked him, saying, Teacher, Moses wrote unto us, that if a man’s brother die, having a wife, and he be childless, his brother should take the wife, and raise up seed unto his brother.
And if the man like not to take his brother’s wife, then his brother’s wife shall go up to the gate unto the elders, and say, My husband’s brother refuseth to raise up unto his brother a name in Israel; he will not perform the duty of a husband’s brother unto me.
