2 Kings 10:25

“And he who sacrifices to any god, other than to Yahweh alone, shall be devoted to destruction.

And the king said to the guards who were standing by him, “Turn around and put the priests of Yahweh to death because their hand also is with David and because they knew that he was fleeing and did not reveal it in my ears.” But the servants of the king were not willing to send forth their hands to fall upon the priests of Yahweh.

Then Elijah said to them, “Seize the prophets of Baal; do not let one of them escape.” So they seized them; and Elijah brought them down to the brook Kishon, and slaughtered them there.

“And it will be that the one who escapes from the sword of Hazael, Jehu shall put to death, and the one who escapes from the sword of Jehu, Elisha shall put to death.

And all the priests of the high places who were there he slaughtered on the altars and burned human bones on them. Then he returned to Jerusalem.
