1 Kings 15:25-28

25In the second year of Asa’s reign over Judah, Jeroboam’s son Nadab became the king of Israel; he ruled Israel for two years.

26He did evil in the sight of the Lord. He followed in his father’s footsteps and encouraged Israel to sin.

27Baasha son of Ahijah, from the tribe of Issachar, conspired against Nadab and assassinated him in Gibbethon, which was in Philistine territory. This happened while Nadab and all the Israelite army were besieging Gibbethon.

28Baasha killed him in the third year of Asa’s reign over Judah and replaced him as king.
