2 Kings 15:9
And he did that which was evil in the sight of the LORD, as his fathers had done: he departed not from the sins of Jeroboam the son of Nebat, who made Israel to sin. And he did that which was evil in the sight of the LORD, as his fathers had done: he departed not from the sins of Jeroboam the son of Nebat, who made Israel to sin.
The verse records the reign of Zachariah, who followed Jeroboam II in the dynasty begun by Jehu and who with Shallum stands at the close of that dynasty, after which came the short and troubled reigns of Menahem, Pekahiah, Pekah, and Hoshea. Those last reigns ended when the kingdom of Israel fell to Assyrian invasion begun under Shalmaneser and completed by Sargon, with the tribes carried away into captivity and scattered. The verse belongs to a period of nearly three hundred years that includes the death of Elisha under Jehoash after about sixty years of ministry, with Hosea, Jonah, and Amos prophesying in Israel and Joel, Isaiah, Micah, Jeremiah, Zephaniah, and Nahum prophesying in Judah.
In that same time Judah was ruled by a succession from Ahaziah, Athaliah, Joash, Amaziah, Azariah or Uzziah, Jotham, Ahaz, Hezekiah, Manasseh, Amon, and Josiah to Jehoahaz, prospering under righteous and faithful rulers and falling into calamity when rulers turned to gross idolatry. The verse shows Israel's kings as part of a continuing departure from God in which idolatry led the people astray, and it implies the kingdom could have been strong and stable if the people had followed the Lord's commandments.
