16 And the people heard in the army, saying, Zambri has conspired and smitten the king: and the people of Israel made Ambri the captain of the host king in that day in the camp over Israel.
17 And Ambri went up, and all Israel with him, out of Gabathon; and they besieged Thersa.
18 And it came to pass when Zambri saw that his city was taken, that he goes into the inner chamber of the house of the king, and burnt the king's house over him, and died.
19 Because of his sins which he committed, doing that which was evil in the sight of the Lord, so as to walk in the way of Jeroboam the son of Nabat, and in his sins wherein he caused Israel to sin.
20 And the rest of the history of Zambri, and his conspiracies wherein he conspired, behold, are not these written in the book of the chronicles of the kings of Israel?
