Contradiction with Genesis 26:24
In Genesis 26:24, God reassures Isaac of the covenant with Abraham, which creates a lineage context contrasting with the identity aspect of "Reuel" in Exodus 2:18, due to differing family affiliations.
Genesis 26:24: And the LORD appeared unto him the same night, and said, I [am] the God of Abraham thy father: fear not, for I [am] with thee, and will bless thee, and multiply thy seed for my servant Abraham's sake.
Contradiction with Numbers 10:29
Numbers 10:29 names Hobab as the son of Reuel, raising confusion with the identity and familial role in Exodus 2:18, as it refers to Reuel as the priest of Midian's "father's house."
Numbers 10:29: And Moses said unto Hobab, the son of Raguel the Midianite, Moses' father in law, We are journeying unto the place of which the LORD said, I will give it you: come thou with us, and we will do thee good: for the LORD hath spoken good concerning Israel.
Contradiction with Judges 4:11
Judges 4:11 refers to Hobab as Moses' father-in-law, creating a contradiction with Exodus 2:18 where Reuel is identified in that role.
Judges 4:11: Now Heber the Kenite, [which was] of the children of Hobab the father in law of Moses, had severed himself from the Kenites, and pitched his tent unto the plain of Zaanaim, which [is] by Kedesh.
