Ruth 4:6

Boaz Redeems Ruth

⁵ Then Boaz said, “On the day you buy the field from the hand of Naomi, you must also acquire Ruth the Moabitess, the widow of the deceased, in order to raise up the name of the deceased on his inheritance.” ⁶ The closest relative said, “I cannot redeem it for myself, because I would jeopardize my own inheritance. Redeem it for yourself; you may have my right of redemption, for I cannot redeem it.” ⁷ Now this was the custom in former times in Israel concerning the redemption and the exchange of land to confirm any matter: a man removed his sandal and gave it to another; and this was the manner of attestation in Israel.

Leviticus 25:25

‘If a fellow countryman of yours becomes so poor he has to sell part of his property, then his nearest kinsman is to come and buy back what his relative has sold.

Ruth 3:13

Remain this night, and when morning comes, if he will redeem you, good; let him redeem you. But if he does not wish to redeem you, then I will redeem you, as the Lord lives. Lie down until morning.”
