In the twelfth: In 2Ki 15:30, this is said to be "the twentieth year of Jotham," which Calmet thus reconciles: "Hosea conspired against Pekah, the 20th year of the reign of this prince, which was the 18th of Jotham, king of Judah. Two years after this, that is, the 4th of Ahaz and the 20th of Jotham, Hosea made himself master of a part of the kingdom, according to 2Ki 15:30. Finally, the 12th year of Ahaz, Hosea had peaceable possession of the whole kingdom, agreeably to 2Ki 17:1."
Hoshea: "After an interregnum, 2Ki 15:30; 2Ki 18:9." 2Ki 17:1
