Nadab son of Jeroboam began to rule over Israel in the second year of King Asa's reign in Judah. He reigned in Israel two years.
But he did what was evil in the LORD's sight and followed the example of his father, continuing the sins of idolatry that Jeroboam had led Israel to commit.
Then Baasha son of Ahijah, from the tribe of Issachar, plotted against Nadab and assassinated him while he and the Israelite army were laying siege to the Philistine town of Gibbethon.
Baasha killed Nadab in the third year of King Asa's reign in Judah, and he became the next king of Israel.
He immediately killed all the descendants of King Jeroboam, so that not one of the royal family was left, just as the LORD had promised concerning Jeroboam by the prophet Ahijah from Shiloh.
This was done because Jeroboam had aroused the anger of the LORD, the God of Israel, by the sins he had committed and the sins he had led Israel to commit.
The rest of the events in Nadab's reign and all his deeds are recorded in The Book of the History of the Kings of Israel.
There was constant war between Asa and King Baasha of Israel.
