Contradiction with Exodus 2:21
Contrary to Genesis 29:12, where Jacob's marriage was arranged among kin, Moses marries Zipporah, a Midianite, not from his own family.
Exodus 2:21: And Moses was content to dwell with the man: and he gave Moses Zipporah his daughter.
Contradiction with Leviticus 18:6
This verse prohibits uncovering the nakedness of close relatives, which contrasts with Jacob marrying his first cousins as in Genesis 29:12.
Leviticus 18:6: None of you shall approach to any that is near of kin to him, to uncover [their] nakedness: I [am] the LORD. [near...: Heb. remainder of his flesh]
Contradiction with Deuteronomy 7:3

Deuteronomy 7:3: Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.
Contradiction with 1 Corinthians 7:39
States a widow is free to marry anyone she wishes within the Lord, suggesting individual choice on marriage versus familial ties seen in Genesis 29:12.
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 2 Corinthians 6:14
Advises against being unequally yoked with unbelievers, which may contradict the familial marriage focus seen in Genesis 29:12 when faith alignment isn't mentioned.
2 Corinthians 6:14: Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
