Marry <06566 03671> [spread therefore.]
Hebrew "spread thy wing;" the emblem of protection; and a metaphor taken from the young of fowls, which run under the wings of their mother from birds of prey. Even to the present day, when a Jew marries a woman, he throws the skirts of his {talith} over her, to signify that he has taken her under his protection.
guardian of the family interests <01350> [a near kinsman. or, one that has right to redeem.]
Ruth 4:6
unable ........................ unable <03201> [I cannot.]
The Targum seems to give the proper sense of this passage: "I cannot redeem it, because I have a wife already; and it is not fit for me to bring another into my house, lest brawling and contention arise in it; and lest I hurt my own inheritance. Do thou redeem it, for thou has no wife; which hinders me from redeeming it."
