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.

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.

And the kinsman said, I cannot redeem it for myself,.... On such a condition, because he had a wife, as the Targum suggests; and to take another would, as that intimates, tend to introduce contention into his family, and make him uncomfortable; so Josephus says (h), he had a wife and children, for that reason it was not convenient for him to take the purchase on such a condition:

lest I mar my own inheritance; he considered, that as he had a wife and children already and as he might have more by marrying Ruth, his family expenses would be increased, and his estate diminished; and what would remain must be divided among many, and this estate in particular go to Ruth's firstborn, whereby his own inheritance would be scattered and crumbled, and come to little or nothing; add to all which, he might suppose that her ancient mother Naomi would be upon his hands to maintain also:

redeem thou my right for thyself which I am ready to give up to thee, for thou hast no wife, as the Targum expresses it:

for I can not redeem it; in the circumstances I am, and upon the condition annexed to the purchase.

(h) Antiqu. l. 5. c. 9. sect. 4.

The redeemer admitted the justice of this demand, from which we may see that the thing passed as an existing right in the nation. But as he was not disposed to marry Ruth, he gave up the redemption of the field.

Ruth 4:6-13

"I cannot redeem it for myself, lest I mar mine own inheritance." The redemption would cost money, since the yearly produce of the field would have to be paid for up to the year of jubilee. Now, if he acquired the field by redemption as his own permanent property, he would have increased by so much his own possessions in land. But if he should marry Ruth, the field so redeemed would belong to the son whom he would beget through her, and he would therefore have parted with the money that he had paid for the redemption merely for the son of Ruth, so that he would have withdrawn a certain amount of capital from his own possession, and to that extent have detracted from its worth. "Redeem thou for thyself my redemption," i.e., the field which I have the first right to redeem.

And the kinsman said, I cannot redeem it for myself, lest I mar mine own inheritance: redeem thou my right to thyself; for I cannot redeem it.

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.

Ru 4:6-8. He Refuses the Redemption.

6. The kinsman said, I cannot redeem it ., lest I mar mine own inheritance-This consequence would follow, either, first, from his having a son by Ruth, who, though heir to the property, would not bear his name; his name would be extinguished in that of her former husband; or, secondly, from its having to be subdivided among his other children, which he had probably by a previous marriage. This right, therefore, was renounced and assigned in favor of Boaz, in the way of whose marriage with Ruth the only existing obstacle was now removed.

4:1-8 This matter depended on the laws given by Moses about inheritances, and doubtless the whole was settled in the regular and legal manner. This kinsman, when he heard the conditions of the bargain, refused it. In like manner many are shy of the great redemption; they are not willing to espouse religion; they have heard well of it, and have nothing to say against it; they will give it their good word, but they are willing to part with it, and cannot be bound to it, for fear of marring their own inheritance in this world. The right was resigned to Boaz. Fair and open dealing in all matters of contract and trade, is what all must make conscience of, who would approve themselves true Israelites, without guile. Honesty will be found the best policy.
