Contradiction with Leviticus 25:25
Leviticus specifies that it is a close relative's responsibility to redeem a property once sold, while in Ruth 4:3, the process seems more transactional and involves negotiations with a kinsman, showing differing redemption practices.
Leviticus 25:25: If thy brother be waxen poor, and hath sold away [some] of his possession, and if any of his kin come to redeem it, then shall he redeem that which his brother sold.
