Contradiction with Numbers 18:7
Numbers 18:7 restricts the priestly service only to Aaron and his sons, yet Numbers 3:10 mentions appointing Aaron and his sons for the priest's office.
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 Exodus 28:1
Exodus 28:1 assigns the priesthood solely to Aaron and his sons without mentioning the Levites as a gift for Aaron, which Numbers 3:10 outlines.
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 Hebrews 7:12
Hebrews 7:12 discusses a change in the priesthood and hence the law, which contradicts the permanent establishment of the priestly services outlined in Numbers 3:10.
Hebrews 7:12: For the priesthood being changed, there is made of necessity a change also of the law.
Contradiction with 1 Peter 2:9
1 Peter 2:9 indicates a general priesthood of all believers, contrasting the exclusive appointment of Aaron and his sons in Numbers 3:10.
1 Peter 2:9: But ye [are] a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: [peculiar: or, purchased] [praises: or, virtues]
Paradox #1
Numbers 3:10 designates only specific descendants of Aaron to serve as priests, meaning that others cannot serve in this role. However, elsewhere in the Bible, it is suggested that all believers can be seen as priests in a spiritual sense. This might seem contradictory because one part of the Bible restricts priesthood to a specific lineage, while another suggests a more inclusive priesthood.
Paradox #2
The contradiction or conflict could be that the verse assigns a role that allows only a specific group to hold a certain religious position, potentially leading to issues of exclusivity and inequality. This exclusivity might seem unfair or inconsistent with the idea of equal opportunity for all people, which can conflict with modern views on equality and non-discrimination.
