Contradiction with Numbers 18:7
This verse explicitly assigns the responsibility of priesthood to Aaron and his sons, highlighting a unique honor, while Numbers 16:9 implies that Levites already have a significant role, not limited to priesthood.
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 Hebrews 7:11-12
This verse discusses the need for a new priesthood through Melchizedek because the Levitical priesthood was insufficient for perfection, contradicting Numbers 16:9's implication of the sufficiency of the Levitical role.
Hebrews 7:11-12: If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need [was there] that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
Contradiction with 1 Samuel 8:7
This verse indicates that the people's rejection of Samuel's leadership constitutes a rejection of God's chosen order, contradicting Numbers 16:9, which implies contentment with divinely appointed roles.
1 Samuel 8:7: And the LORD said unto Samuel, Hearken unto the voice of the people in all that they say unto thee: for they have not rejected thee, but they have rejected me, that I should not reign over them.
Contradiction with Exodus 19:6
This verse calls all of Israel a kingdom of priests, suggesting a more universal priesthood contrary to the special privilege of the Levites described in Numbers 16:9.
Exodus 19:6: And ye shall be unto me a kingdom of priests, and an holy nation. These [are] the words which thou shalt speak unto the children of Israel.
Contradiction with Isaiah 66:21
This verse suggests that God can choose priests from non-Levites, contradicting the specific elevation of Levites in Numbers 16:9.
