Shallum, son of Jabesh

Shallum conspired against Zechariah, king of Israel, and assassinated him to usurp the throne (2Ki 15:10). Assyrian records call Shallum “the son of nobody” indicating that he was not of royal lineage. His treacherous act fulfilled the prophecy regarding Jehu's dynasty predicting that his sons would sit on the throne of Israel only until the fourth generation (2Ki 10:30).

“Shallum the son of Jabesh became king in the thirty-ninth year of Uzziah king of Judah; and he reigned a full month in Samaria.” (2Ki 15:13)

The son of Jabesh's evil deed did not go unpunished as his reign was in turn cut short by assassination:

“For Menahem the son of Gadi went up from Tirzah, came to Samaria, and struck Shallum the son of Jabesh in Samaria and killed him; and he reigned in his place.” (2Ki 15:14)

Menahem likely had been a military governor under Zechariah, with his forces stationed at Tirzah, the former capital of Israel (1Ki 14:17; 1Ki 15:21, 33).
