King of Israel succeeded his father Jeroboam 2,773 B. C., and reigned six months. He did evil in the sight of the Lord, and Shallum son of Jabesh conspired against him, killed him in public, and reigned in his stead. Thus was fulfilled what the Lord had foretold to Jehu, that his children should sit on the throne of Israel to the fourth generation, 2 Kings 14:29; 15:8-11.

Zachariah
(remembered by Jehovah ), or properly Zechariah.
Son of Jeroboam II., fourteenth king of Israel, and the last of the house of Jehu. There is a difficulty about the date of his reign. Most chronologers assume an interregnum of eleven years between Jeroboam’s death and Zachariah’s accession. The latter event took place B.C. 772-1. His reign lasted only six months. He was killed in a conspiracy of which Shallum was the head, and by which the prophecy in (2 Kings 10:30) was accomplished,
The father of Abi or Abijah, Hezekiah’s mother. (2 Kings 18:2)
