Contradiction with Deuteronomy 16:16
Contradicts by specifying that only males must appear before the Lord, altering the inclusivity of 2 Chronicles 30:5.
Deuteronomy 16:16: Three times in a year shall all thy males appear before the LORD thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty:
Contradiction with Deuteronomy 12:5
Contradicts by indicating that you should only seek the place which the Lord shall choose, differing from the collective mandate in 2 Chronicles 30:5.
Deuteronomy 12:5: But unto the place which the LORD your God shall choose out of all your tribes to put his name there, [even] unto his habitation shall ye seek, and thither thou shalt come:
Contradiction with Exodus 23:17
Contradicts as it mandates appearance thrice in a year, differing in frequency from 2 Chronicles 30:5.
Exodus 23:17: Three times in the year all thy males shall appear before the Lord GOD.
Contradiction with 2 Kings 23:21
Contradicts by specifying the observance in Jerusalem under King Josiah, not aligning with the broader call in 2 Chronicles 30:5.
2 Kings 23:21: And the king commanded all the people, saying, Keep the passover unto the LORD your God, as [it is] written in the book of this covenant.
Paradox #1
2 Chronicles 30:5 talks about celebrating Passover in a way that involves inviting people from both Judah and Israel after they had split into two separate kingdoms. A possible contradiction is that this event assumes cooperation between the two kingdoms, which were often at odds or in conflict with each other during that time period. The invitation to people in the northern kingdom of Israel might not have been a common occurrence.
