II Kings 12:19–21

And the rest of the acts of Joas, and all that he did, are they not written in the book of the words of the days of the kings of Juda? 20And his servants arose, and conspired among themselves, and slew Joas, in the house of Mello, in the descent of Sella. 21For Josachar the son of Semaath, and Jozabad the son of Somer his servant, struck him, and he died: and they buried him with his fathers in the city of David; and Amasias, his son, reigned in his stead.
