And Naomi said unto her daughter in law, Blessed be he of the LORD, who hath not left off his kindness to the living and to the dead. And Naomi said unto her, The man is near of kin unto us, one of our next kinsmen. To the living and to the dead - Naomi and Ruth were the living; and they were also the representatives of Elimelech and Mahlon, who were dead. Naomi was of the family; and Ruth, though not of the family, was a representative of one of its deceased branches, being the widow of Mahlon.
One of our next kinsmen - מגאלינו miggoaleynu, of our redeemers, one who has the right to redeem the forfeited inheritance of the family. The word גאל goel signifies a near kinsman - one who by the Mosaic law had a right to redeem an inheritance, and also was permitted to vindicate or revenge the death of his relation by killing the slayer, if he found him out of the cities of refuge.
In order to prevent families from running to decay, if a brother died childless, the next unmarried brother took his widow; and the children from that marriage were reputed the children of the deceased brother. The office of the next akin was threefold:
1. It belonged to him to buy back the forfeited inheritance, or the liberty of him who had been obliged to sell himself for a servant.
2. It was his right to avenge the blood of any of the family who had been killed, by killing the murderer.
3. It belonged to him to take the widow of a deceased brother or relative, if he died childless.
If the nearest akin in any case refused, he was treated with indignity, lost his right to the inheritance, and the next akin to him might come forward and take the widow, etc., as in the case of Boaz. See Ruth 4:4-10.
