2KI 23:16

16 Then Josiah looked around and saw some tombs there on the hill. He commanded his men to take the bones out of those tombs and burn them on the altar. By doing that, he desecrated the altar. That was what a prophet had predicted many years before when Jeroboam [#1] was standing close to that altar at a festival. Then Josiah looked up and saw the tomb of the prophet who had predicted that.
