Contradiction with Matthew 23:23
While Numbers 4:45 emphasizes specific duties and rituals, Matthew 23:23 suggests the importance of broader principles such as justice, mercy, and faith over ritual particulars.
Matthew 23:23: Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier [matters] of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone. [anise: Gr. dill]
Contradiction with Galatians 3:24-25
Numbers 4:45 involves adherence to the law for Levite duties, while Galatians 3 speaks of the law as a guardian until Christ, suggesting the era of such detailed observance is fulfilled in Christ.
Galatians 3:24-25: Wherefore the law was our schoolmaster [to bring us] unto Christ, that we might be justified by faith.
Contradiction with Hebrews 7:18-19
Numbers 4:45 is prescriptive about levitical practice, whereas Hebrews 7:18-19 describes the law as set aside due to its weakness and introducing a better hope.
Hebrews 7:18-19: For there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof.
Contradiction with Colossians 2:16-17
The prescriptive nature of Numbers and its laws about duties are contrasted with Colossians urging believers not to let anyone pass judgment on matters of ritual observance which are a shadow.
Colossians 2:16-17: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Contradiction with Romans 10:4
Numbers 4:45 involves a technical aspect of the law, but Romans 10:4 states that Christ is the end of the law so that there may be righteousness for everyone who believes.
Romans 10:4: For Christ [is] the end of the law for righteousness to every one that believeth.
