Matthew 22:24

Then Judah said to Onan, “Go in to your brother’s wife, and perform your duty as a brother-in-law to her, and raise up a seed for your brother.”

“If brothers live together and one of them dies and has no son, then the wife of the one who died shall not be married outside the family to a strange man. Her husband’s brother shall go in to her and take her to himself as wife and perform the duty of a husband’s brother to her.

“Stay this night, and it will be in the morning that, if he will redeem you, good; let him redeem you. But if he does not desire to redeem you, then I will redeem you, as Yahweh lives. Lie down until morning.”

Then Boaz said, “On the day you acquire the field from the hand of Naomi, you must also acquire Ruth the Moabitess, the widow of the one who had died, in order to raise up the name of the one who had died, on behalf of his inheritance.”

And for this reason He is the mediator of a new covenant, so that, since a death has taken place for the redemption of the trespasses that were committed under the first covenant, those who have been called may receive the promise of the eternal inheritance.
