1 Kings 18:40-41

Then Elijah said to them, “Seize the prophets of Baal; do not let one of them escape.” They seized them; and Elijah brought them down to the brook Kishon, and [as God’s law required] killed them there. [Deut 13:5, 12-15; 18:20] Now Elijah said to Ahab, “Go up, eat and drink, for there is the sound of the roar of an abundance of rain.”
