2 Kings 15:10-12

15:10 Shallum son of Jabesh conspired against him; he assassinated him in Ibleam and took his place as king. 15:11 The rest of the events of Zechariah’s reign are recorded in the scroll called the Annals of the Kings of Israel. 15:12 His assassination brought to fulfillment the Lord’s word to Jehu, “Four generations of your descendants will rule over Israel.” That is exactly what happened.
