Moreover by the prophet Jehu the son of Hanani the word of Yahweh came against Baasha and against his house, both because of all the evil that he did in the eyes of Yahweh, making him angry by the work of his hands in being like the house of Jeroboam, and because he struck it down. Bible

”because he struck it.” Baasha not only murdered Nadab the son of Jeroboam to become king (1 King 15:27), he went on to murder all the house of Jeroboam (1 Kings 15:29).
