Numbers 25:1-5

While Israel remained at Shittim, the people began to commit infidelity with the daughters of Moab.

For they invited the people to the sacrifices of their gods, and the people ate and bowed down to their gods.

So Israel became followers of Baal of Peor, and the Lord was angry with Israel.

And the Lord said to Moses, “Take all the leaders of the people and execute them in broad daylight before the Lord, so that the fierce anger of the Lord may turn away from Israel.”

So Moses said to the judges of Israel, “Each of you kill his men who have become followers of Baal of Peor.”
