Contradiction with Exodus 12:14
This verse establishes the Passover as a perpetual ordinance to be observed throughout the generations, which could contradict the implication in 2 Kings 23:22 that the Passover described there was unprecedented.
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
These verses command the Israelites to keep the Passover at its appointed time, which could be seen as a contradiction if 2 Kings 23:22 suggests the Passover was not observed regularly prior to Josiah.
Numbers 9:2-3: Let the children of Israel also keep the passover at his appointed season.
Contradiction with 2 Chronicles 30:1
King Hezekiah invited all Israel and Judah to celebrate the Passover, contradicting the notion that such a Passover had not been held since the judges.
2 Chronicles 30:1: And Hezekiah sent to all Israel and Judah, and wrote letters also to Ephraim and Manasseh, that they should come to the house of the LORD at Jerusalem, to keep the passover unto the LORD God of Israel.
Contradiction with 2 Chronicles 35:18
This verse mirrors the account in 2 Kings 23:22 but from a different chronicle perspective, which could imply a historical contradiction between different accounts of the Passover practices.
2 Chronicles 35:18: And there was no passover like to that kept in Israel from the days of Samuel the prophet; neither did all the kings of Israel keep such a passover as Josiah kept, and the priests, and the Levites, and all Judah and Israel that were present, and the inhabitants of Jerusalem.

Paradox #1
Some scholars point out a contradiction regarding the celebration of Passover in 2 Kings 23:22. It suggests that the Passover had not been celebrated like this since the days of the judges or the kings of Israel. However, other parts of the Bible, like 2 Chronicles 30, mention Passover celebrations during King Hezekiah's reign, raising questions about what is described as unprecedented in 2 Kings.
