Ruth 4:6

I cannot redeem it for myself - The Targum gives the proper sense of this passage: "And the kinsman said, On this ground I cannot redeem it, because I have a wife already; and I have no desire to take another, lest there should be contention in my house, and I should become a corrupter of my inheritance. Do thou redeem it, for thou hast no wife; for I cannot redeem it." This needs no comment. But still the gloss of the Targum has no foundation in the law of Moses. See the law, Deuteronomy 25:5-9.

I mar mine own inheritance - The meaning of these words is doubtful. Some explain them by saying that the גאל gā'al had a wife and children already, and would not introduce strife into his family. Others think that there was a risk (which he would not incur) of the go'el's own name being blotted out from his inheritance Ruth 4:10. Others take the word translated as "mar" in a sense of wasting or spending. If he had to find the purchase-money, and support Naomi and Ruth, his own fortune would be broken down, if, as is likely, he was a man of slender means. Boaz, being "a mighty man of wealth," could afford this.

Redeem thou my right ... - Literally, redeem my redemption - perform that act of redemption which properly belongs to me, but which I cannot perform.

4:6 Mar - Either because having no children of his own, he might have one, and but one son by Ruth, who, though he should carry away his inheritance, yet would not bear his name, but the name of Ruth's husband; and so by preserving another man's name, he should lose his own.Or, because as his inheritance would be but very little increased by this marriage, so it might be much diminished by being divided amongst his many children, which he possibly had already, and might probably have more by Ruth. My right - Which I freely resign to thee.
