twelfth year of Joram
2 Kings 8:25
8:25 twelfth year of Joram. Ahaziah is said in this verse to have become king of Judah in the twelfth year of Joram, king of Israel. Yet II Kings 9:29 says it was in the eleventh year. Both are correct—the first using the post-accession year as the starting point, the latter using the actual accession year—both systems being used in the ancient world.
