Read Ruth 4:6 Using Other Translations
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.
Then the redeemer said, "I cannot redeem it for myself, lest I impair my own inheritance. Take my right of redemption yourself, for I cannot redeem it."
“Then I can’t redeem it,” the family redeemer replied, “because this might endanger my own estate. You redeem the land; I cannot do it.”
