The Lord said to Jehu, “You have done well. You have done the things that I say are good. You destroyed Ahab’s family the way I wanted you to. So your descendants [131] will rule Israel for four generations.”
All the great things that Jeroboam did are written in the book The History of the Kings of Israel. This includes the story about Jeroboam winning back Damascus and Hamath for Israel. (These cities had belonged to Judah.)
