Contradiction with Exodus 6:25
Exodus 6:25 introduces Eleazar, son of Aaron, and his marriage to Putiel's daughter, whereas Exodus 6:24 focuses on the sons of Korah, showing differing family lineages within the same broader narrative.
Exodus 6:25: And Eleazar Aaron's son took him [one] of the daughters of Putiel to wife; and she bare him Phinehas: these [are] the heads of the fathers of the Levites according to their families.
Contradiction with Numbers 16:32
This verse describes the earth swallowing Korah and his followers, contradicting Exodus 6:24 where the sons of Korah are listed as a lineage, which implies their survival and continuation.
Numbers 16:32: And the earth opened her mouth, and swallowed them up, and their houses, and all the men that [appertained] unto Korah, and all [their] goods.
