Contradiction with Numbers 18:2
Numbers 18:2 allows bringing other tribes alongside the Levites to assist in their duties, while Numbers 3:6 specifies the Levites are solely given to Aaron and his sons for service.
Numbers 18:2: And thy brethren also of the tribe of Levi, the tribe of thy father, bring thou with thee, that they may be joined unto thee, and minister unto thee: but thou and thy sons with thee [shall minister] before the tabernacle of witness.
Contradiction with Exodus 28:1
Exodus 28:1 states that Aaron and his sons are chosen to serve as priests, whereas Numbers 3:6 assigns the Levites to assist them, suggesting a broader role for the Levites beyond just priesthood.
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 Deuteronomy 10:8
Deuteronomy 10:8 outlines the Levites' duty to bear the Ark and stand before God, while Numbers 3:6 assigns them to the service of Aaron and his sons, implying a more limited role.
Deuteronomy 10:8: At that time the LORD separated the tribe of Levi, to bear the ark of the covenant of the LORD, to stand before the LORD to minister unto him, and to bless in his name, unto this day.
Paradox #1
Numbers 3:6 involves assigning the Levites to a specific religious duty. A potential contradiction or conflict might arise if one questions the fairness of assigning an entire group to a religious role based solely on lineage rather than individual choice or calling, which could be seen as conflicting with ideas of personal freedom and equality.
