Contradiction with Deuteronomy 25:5-6
These verses support the concept of a brother marrying his deceased brother's widow to produce an heir, which aligns with Genesis 38:8 rather than contradicting it.
Deuteronomy 25:5-6: 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 22:24
This verse cites the law of a brother marrying his deceased brother's widow, also aligned with Genesis 38:8.
Matthew 22:24: Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother:
Paradox #1
Genesis 38:8 involves a practice called levirate marriage, where a man is expected to marry his deceased brother's widow to produce offspring in his brother's name. The contradiction or conflict could arise when comparing this practice to other parts of the Bible or cultural contexts that do not support or conflict with this tradition. Some may also see inconsistency in how this practice is applied or not applied in different biblical stories or laws.
Paradox #2
Genesis 38:8 could show a moral conflict regarding the obligation of marriage and family duties versus personal choice and consent. In the context of the time, family duties were prioritized, but today this might clash with modern views on individual autonomy and consensual relationships.
