Contradiction with Leviticus 7:15
Whereas the meat of the sacrifice in Numbers 9:12 must not be left until the morning, Leviticus 7:15 allows the flesh of the peace offerings for thanksgiving to be eaten on the same day with none to remain until the morning.
Leviticus 7:15: And the flesh of the sacrifice of his peace offerings for thanksgiving shall be eaten the same day that it is offered; he shall not leave any of it until the morning.
Contradiction with Deuteronomy 16:4
Numbers 9:12 requires that no bone of the Passover lamb is broken, but Deuteronomy 16:4 states that no leaven should be present within any of the borders of Israel for seven days, and mentions nothing about the bones.
Deuteronomy 16:4: And there shall be no leavened bread seen with thee in all thy coast seven days; neither shall there [any thing] of the flesh, which thou sacrificedst the first day at even, remain all night until the morning.
Contradiction with John 19:36
While Numbers 9:12 relates to the Passover observance, John 19:36 connects not breaking a bone with the crucifixion of Jesus, suggesting a New Testament interpretation.
John 19:36: For these things were done, that the scripture should be fulfilled, A bone of him shall not be broken.

1 Corinthians 5:7: Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: [is sacrificed; or, is slain]
