Hos 1:1 The word of the Lord that came to Hosea, the son of Beeri, in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, and in the days of Jeroboam the son of Joash, king of Israel.
The order and detail of kings listed suggests Hosea’s prophecy may have been intended as a lesson for Judah even more than Israel. It could mean Hosea was actual from Judah, though this seems less likely. There is also a time discrepancy between the kings listed. These details may suggest the book was intended to be more poetic than literal. Regardless, the information here dates the book to the mid to late 8th century in the period leading up to the fall of Samaria in 722.
