'Redeem' 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.”

So I thought to let you hear of it, saying, ‘Buy it in the presence of those sitting here, and before the elders of my people. If you will redeem it, redeem it; but if not, then tell me, so that I may know; for there is no one besides you to redeem it, and I am [next of kin] after you.’” And he said, “I will redeem it.”

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.”
