Contradiction with Exodus 28:1
Exodus 28:1 appoints Aaron and his sons to the priesthood forever, contrasting with the restriction in Ezekiel 44:13.
Exodus 28:1: And take thou unto thee Aaron thy brother, and his sons with him, from among the children of Israel, that he may minister unto me in the priest's office, [even] Aaron, Nadab and Abihu, Eleazar and Ithamar, Aaron's sons.
Contradiction with Numbers 18:7
Numbers 18:7 gives a perpetual priesthood to the Levites, while Ezekiel 44:13 excludes certain Levites from ministering.
Numbers 18:7: Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office [unto you] as a service of gift: and the stranger that cometh nigh shall be put to death.
Contradiction with Psalm 110:4
Psalm 110:4 speaks of an eternal priesthood, while Ezekiel 44:13 imposes a restriction on some priests.
Psalm 110:4: The LORD hath sworn, and will not repent, Thou [art] a priest for ever after the order of Melchizedek.
Contradiction with Hebrews 7:21
Hebrews 7:21 refers to an unchangeable priesthood, yet Ezekiel 44:13 changes who can minister.
Hebrews 7:21: (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou [art] a priest for ever after the order of Melchisedec:) [without...: or, without swearing of an oath]
Paradox #1
Ezekiel 44:13 issues a rule related to certain people not serving in specific sacred roles. The potential theological inconsistency arises when comparing this to other biblical passages that emphasize forgiveness and restoration. One might question how a merciful and forgiving God can impose lifelong restrictions on service based on past actions, seemingly conflicting with themes of redemption present in other parts of the Bible.
Paradox #2
The contradiction in Ezekiel 44:13 could be seen in how it restricts certain individuals from performing sacred duties due to past actions, potentially conflicting with the ideas of forgiveness and redemption that are also present in the Bible. This raises questions about whether past mistakes should permanently disqualify someone from serving in a religious role, especially when other parts of the Bible emphasize repentance and the possibility of starting anew.
