Matthew

If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband’s brother shall go in unto her, and take her to him to wife, and perform the duty of an husband’s brother unto her.

And his name shall be called in Israel, The house of him that hath his shoe loosed.

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.

Saying, Master, Moses wrote unto us, If any man’s brother die, having a wife, and he die without children, that his brother should take his wife, and raise up seed unto his brother.

Thou shalt not uncover the nakedness of thy brother’s wife: it is thy brother’s nakedness.
