Contradiction with Exodus 12:14
This verse establishes the Passover as a perpetual ordinance to be observed at a specific time, contradicting the decision in 2 Chronicles 30:4 to change the timing.
Exodus 12:14: And this day shall be unto you for a memorial; and ye shall keep it a feast to the LORD throughout your generations; ye shall keep it a feast by an ordinance for ever.
Contradiction with Numbers 9:2-3
This passage commands the observance of Passover in the first month, differing from the alternate timing decided in 2 Chronicles 30:4.
Numbers 9:2-3: Let the children of Israel also keep the passover at his appointed season.
Contradiction with Leviticus 23:5
This verse specifies the exact date of the Passover, which contrasts with the decision-making flexibility seen in 2 Chronicles 30:4.
Leviticus 23:5: In the fourteenth [day] of the first month at even [is] the LORD'S passover.
Contradiction with Deuteronomy 16:1
Commands the observance of Passover in the month of Abib, which is at odds with changing the timing as done in 2 Chronicles 30:4.
Deuteronomy 16:1: Observe the month of Abib, and keep the passover unto the LORD thy God: for in the month of Abib the LORD thy God brought thee forth out of Egypt by night.
