Zechariah, son of Jeroboam II

“In the thirty-eighth year of Azariah (Uzziah) king of Judah, Zechariah the son of Jeroboam reigned over Israel in Samaria six months. And he did evil in the sight of the LORD, as his fathers had done; he did not depart from the sins of Jeroboam the son of Nebat, who had made Israel sin.” (2Ki 15:8-9)

Zechariah's reign spanned the last month's of Azariah's (Uzziah) 38th year (2Ki 15:8) and the first months of the following year (2Ki 15:9).

“Then Shallum the son of Jabesh conspired against him, and struck and killed him in front of the people; and he reigned in his place.” (2Ki 15:10)

Shallum murdered Zechariah and usurped the throne of Israel. Assyrian records call Shallum “the son of nobody” indicating that he was not of royal lineage. Zechariah was the fourth and final generation of Jehu's dynasty, and his assassination fulfilled the prophecy (2Ki 10:30).

“This was the word of the LORD which He spoke to Jehu, saying, Your sons shall sit on the throne of Israel to the fourth generation. And so it was.” (2Ki 15:12)
