'Right' in the Bible

Naomi said to her daughter-in-law, “May he be blessed of the Lord who has not ceased His kindness to the living and to the dead.” Again Naomi said to her, “The man is one of our closest relatives, one who has the right to redeem us.”

The closest relative (redeemer) said, “I cannot redeem it for myself, because [by marrying a Moabitess] I would jeopardize my own inheritance. Take my right of redemption (purchase) yourself, because I cannot redeem it.”
