Numbers 25:3-5

³So Israel had relations with the women of Moab in honour of the Baal of Peor: and the Lord was moved to wrath against Israel.

⁴Then the Lord said to Moses, Take all the chiefs of the people, hanging them up in the sun before the Lord, so that the wrath of the Lord may be turned from Israel.

⁵So Moses said to the judges of Israel, Let everyone put to death those of his men who have had relations with the women of Moab in honour of the Baal of Peor.
