Matthew Poole and continuators on Ruth 4:6

6 ¶ And the kinsman said, I cannot redeem it for my self, lest I mar mine own inheritance : redeem thou my right to thy self, for I cannot redeem it.

Either, First, 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 should not bear his Name, but the Name of Ruths Husband; and so by preserving another Mans Name, he should lose his own. Or, Secondly, 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.

Which I freely Renounce and Resign to thee.
