Numbers 25:2-4

Amplified Bible, Classic Edition

² Who invited the [Israelites] to the sacrifices of their gods, and [they] ate and bowed down to Moab’s gods.

³ So Israel joined himself to [the god] Baal of Peor. And the anger of the Lord was kindled against Israel.

⁴ And the Lord said to Moses, Take all the leaders or chiefs of the people, and hang them before the Lord in the sun [after killing them], that the fierce anger of the Lord may turn away from Israel.
