Bible Verses About Regicide: Of Elah

His servant Zimri, captain of half his chariots, conspired against him. Now he was in Tirzah, drinking himself drunk in the house of Arza, who was over the household in Tirzah:

and Zimri went in and struck him, and killed him, in the twenty-seventh year of Asa king of Judah, and reigned in his place.

When he began to reign, as soon as he sat on his throne, he struck all the house of Baasha: he didn’t leave him a single one who urinates on a wall, neither of his relatives, nor of his friends.
