Contradiction with Exodus 20:8
Exodus 20:8 establishes the Sabbath as a day of rest, which may seem at odds with Numbers 28:9 that prescribes work for preparing sacrifices on the Sabbath.
Exodus 20:8: Remember the sabbath day, to keep it holy.
Contradiction with Isaiah 1:11
Isaiah 1:11 suggests that God takes no pleasure in the burnt offerings and sacrifices, which contradicts Numbers 28:9 where sacrifices are commanded.
Isaiah 1:11: To what purpose [is] the multitude of your sacrifices unto me? saith the LORD: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats. [he goats: Heb. great he goats]
Contradiction with Amos 5:21-22
Amos 5:21-22 indicates God's rejection of Israel's feasts and burnt offerings, contrasting with Numbers 28:9's instructions to perform such offerings on the Sabbath.
Amos 5:21-22: I hate, I despise your feast days, and I will not smell in your solemn assemblies. [in...: or, your holy days]
Contradiction with Matthew 12:7
Matthew 12:7 emphasizes mercy over sacrifice, which can be viewed as conflicting with the directive in Numbers 28:9 for Sabbath sacrifices.
Matthew 12:7: But if ye had known what [this] meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless.
