2 Kings 12:20-21

And his servants arose, and made a conspiracy, and slew Joash in the house of Millo, which goeth down to Silla. For Jozachar the son of Shimeath, and Jehozabad the son of Shomer, his servants, smote him, and he died; and they buried him with his fathers in the city of David: and Amaziah his son reigned in his stead.
