1 Kings 16:9-13

9And his servant Zimri, captain of half his chariots, conspired against him, as he was in Tirzah, drinking himself drunk in the house of Arza steward of his house in Tirzah.1 10And Zimri went in and smote him, and killed him, in the twenty and seventh year of Asa king of Judah, and reigned in his stead.

11And it came to pass, when he began to reign, as soon as he sat on his throne, that he slew all the house of Baasha: he left him not one that pisseth against a wall, neither of his kinsfolks, nor of his friends.2 12Thus did Zimri destroy all the house of Baasha, according to the word of Yhwh, which he spake against Baasha by Jehu the prophet,3 13For all the sins of Baasha, and the sins of Elah his son, by which they sinned, and by which they made Israel to sin, in provoking Yhwh God of Israel to anger with their vanities.
