Here’s Hebrews vs Leviticus
Hebrews 10:4 [It] is impossible for the blood of bulls and goats to take away sins. ... 12 Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins.
Leviticus 16:27 The bull and the goat for the sin offerings, whose blood was brought into the Most Holy Place to make atonement, must be taken outside the camp; their hides, flesh and offal are to be burned up. ... 30 because on this day [Yom Kippur] atonement will be made for you, to cleanse you. Then, before the LORD, you will be clean from all your sins. ... 34 This is to be a lasting ordinance for you: Atonement is to be made once a year for all the sins of the Israelites." And it was done, as the LORD commanded Moses.
Recap: The Christian writer of Hebrews denounces animal sacrifice. He says animal sacrifice can't remove sin. But before Christianity God put animal sacrifice in place for the removal of sin. It was good enough for God. Thus Hebrews vs Leviticus.
