Ruth 4:5 Meaning and Commentary

Ruth 4:5

Then said Boaz
In order to try the kinsman, whether he would abide by his resolution, he acquaints him with what he had as yet concealed:

what day thou buyest the field of Naomi, thou must buy it also of Ruth
the Moabitess, the wife of the dead;
the wife of Mahlon, who was dead, the eldest son of Naomi, and so his widow, Ruth the Moabitess, had the reversion of the estate; wherefore the purchase must be made of her as well as of Naomi, and the purchase could not be made of her without marrying her; which, though no law obliged to, yet it seems to be a condition of the purchase annexed to it by Naomi, that she would sell it to no man, unless he would consent to marry Ruth, for whose settlement she had a great concern, having been very dutiful and affectionate to her; which is clearly intimated in the next clause:

to raise up the name of the dead upon his inheritance;
and so Naomi had another end to answer thereby, not only to provide a good husband for her daughter-in-law, but to perpetuate the name of her son, agreeably to the design of the law in ( Deuteronomy 25:5 ) .

Ruth 4:5 In-Context

3 And Booz said to the relative, the portion of the field which was our brother Elimelech's which was given to Noemin, now returning out of the land of Moab;
4 and I said, I will inform thee, saying, Buy it before those that sit, and before the elders of my people: if thou wilt redeem it, redeem it, but if thou wilt not redeem it, tell me, and I shall know; for there is no one beside thee to do the office of a kinsman, and I am after thee: and he said, I am , I will redeem it.
5 And Booz said, In the day of thy buying the field of the hand of Noemin and of Ruth the Moabitess the wife of the deceased, thou must also buy her, so as to raise up the name of the dead upon his inheritance.
6 And the kinsman said, I shall not be able to redeem it for myself, lest I mar my own inheritance; do thou redeem my right for thyself, for I shall not be able to redeem .
7 And this in former time the ordinance in Israel for redemption, and for a bargain, to confirm every word: A man loosed his shoe, and gave it to his neighbour that redeemed his right; and this was a testimony in Israel.
