Contradiction with Exodus 13:2
This verse states that all the firstborn belong to God, which contradicts Numbers 3:12 where only the Levites are taken instead of the firstborn.
Exodus 13:2: Sanctify unto me all the firstborn, whatsoever openeth the womb among the children of Israel, [both] of man and of beast: it [is] mine.
Contradiction with Numbers 8:16
This verse emphasizes that the Levites are taken wholly for service, differing slightly from Numbers 3:12, which suggests a substitution for the firstborn rather than exclusive service.
Numbers 8:16: For they [are] wholly given unto me from among the children of Israel; instead of such as open every womb, [even instead of] the firstborn of all the children of Israel, have I taken them unto me.
Contradiction with Hebrews 7:12
This verse speaks to a change in the law and priesthood, contradicting the exclusive role of Levites indicated in Numbers 3:12.
Hebrews 7:12: For the priesthood being changed, there is made of necessity a change also of the law.
Paradox #1
Numbers 3:12 could be seen as conflicting with previous references to the firstborn sons belonging to God, as it introduces the Levites being taken in their place. This might create an inconsistency regarding which group is set apart for God's service.
Paradox #2
Numbers 3:12 may present a contradiction related to the idea of ownership or substitution. The verse suggests God takes the Levites instead of the firstborn of Israel for His service, which raises questions about fairness and the idea of substituting one group for another without individual consent. This might be seen as inconsistent with modern views on personal freedom and equality, where all individuals are considered to have equal rights and autonomy.
