Numbers 25:1-4

While Israel lived in Shittim, the people began to whore with the daughters of Moab. These invited the people to the sacrifices of their gods, and the people ate and bowed down to their gods. So Israel yoked himself to Baal of Peor. And the anger of the LORD was kindled against Israel. And the LORD said to Moses, “Take all the chiefs of the people and hang them in the sun before the LORD, that the fierce anger of the LORD may turn away from Israel.”
