Contradiction with Deuteronomy 25:5
Deuteronomy 25:5 refers to the levirate marriage, where a brother is required to marry his dead brother's widow, while Ruth 4:5 involves Boaz, who is not the direct brother but a kinsman redeemer.
Deuteronomy 25:5: If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her. [her husband's...: or, her next kinsman]
Contradiction with Matthew 19:4-6
Matthew 19:4-6 emphasizes the sanctity and permanence of marriage between a husband and wife, which seems to contrast with Ruth 4:5 where marriage arrangements are negotiated and involve legal redemption.
Matthew 19:4-6: And he answered and said unto them, Have ye not read, that he which made [them] at the beginning made them male and female,
Contradiction with 1 Corinthians 7:39
1 Corinthians 7:39 allows a widow to marry whom she wishes with no obligation to follow a levirate-like arrangement, unlike the situation in Ruth 4:5, where Boaz follows cultural obligations to marry Ruth.
1 Corinthians 7:39: The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord.
Contradiction with Leviticus 25:23-25
Leviticus 25:23-25 discusses rules about land redemption in a Jubilee context, focusing on land not people, contrasting with Ruth 4:5 which intertwines land and marriage redemption.
Leviticus 25:23-25: The land shall not be sold for ever: for the land [is] mine; for ye [are] strangers and sojourners with me. [for ever: or, to be quite cut off: Heb. for cutting off]
Contradiction with Romans 7:3
Romans 7:3 states that a woman is free to marry another if her husband dies, without obligations like those found in Ruth 4:5, which involves duties of kinsman redeemers in marriage.
Romans 7:3: So then if, while [her] husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
Paradox #1
The potential contradiction in this verse could be the tension between following family traditions and individual desires. The obligation to marry to preserve a family name might conflict with personal freedom and genuine romantic interests.
