Not all manuscripts and hense Bible versions read the same in these verses, hense the possibility of a copyist error in some of the manuscripts. Thus you will find these "contradictions" in some Bible versions and not in others. Some of the verses listed are discussed on the following site, which deals with them as being likely copyist errors in certain manuscript traditions. Copyist errors in some manuscripts do not prove that the Bible itself is full of contardictions and historical innacuracies.
- 2 Chronicles 21:20, 22:1-2
- Thirty and two years old was he when he began to reign, and he reigned in Jerusalem eight years, and departed without being desired. Howbeit they buried him in the city of David, but not in the sepulchres of the kings. And the inhabitants of Jerusalem made Ahaziah his youngest son king in his stead: for the band of men that came with the Arabians to the camp had slain all the eldest. So Ahaziah the son of Jehoram king of Judah reigned. Forty and two years old was Ahaziah when he began to reign, and he reigned one year in Jerusalem His mother's name also was Athaliah the daughter of Omri. How can a son be 42 and older than his father who dies at 40? The likely answer is a copyist error in Ahaziah's recorded age. "Forty and two" was likely once "twenty or two" -- the symbols used for these are somewhat similar, see here for a picture, and the parallel verse 2 Kings 8:26 says 22.
- 2 Chronicles 22:2
- Was Ahaziah forty-two or twenty-two (per 2 Kings 8:26) when he ascended the throne? More likely 22, and 2 Chronicles has been hit by a copyist error. See our foundational essay on copyist errors for general background. In favor of the "22" reading in 2 Chronicles: The 2 Kings reading; some LXX and Syriac manuscripts, and that Chronicles calls Ahaziah Jehoram's "youngest son" (22:1) and Jehoram passed away at age 40 (21:20). The numbers in Hebrew for two and four look alike except for a horizontal stroke; see here for a picture.
- 1 Kings 16:23, 28-9
- In the thirty and first year of Asa king of Judah began Omri to reign over Israel, twelve years: six years reigned he in Tirzah...So Omri slept with his fathers, and was buried in Samaria: and Ahab his son reigned in his stead. And in the thirty and eighth year of Asa king of Judah began Ahab the son of Omri to reign over Israel: and Ahab the son of Omri reigned over Israel in Samaria twenty and two years. Seven years, or twelve, for Omri's reign? The likely answer is a copyist error in one of the passages... see here for a picture.
There are other arguments listed in the original post, I may comment if I decide to take the time to go into those issues.
