Numbers 25:3-5

3So Israel yoked themselves to the Baal of Peor. And the Lord’s anger burned against them.

4The Lord said to Moses, “Take all the leaders of these people, kill them and expose them in broad daylight before the Lord, so that the Lord’s fierce anger may turn away from Israel.”

5So Moses said to Israel’s judges, “Each of you must put to death those of your people who have yoked themselves to the Baal of Peor.”
