Numbers 25:3-9

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.”

6Then an Israelite man brought into the camp a Midianite woman right before the eyes of Moses and the whole assembly of Israel while they were weeping at the entrance to the tent of meeting.

7When Phinehas son of Eleazar, the son of Aaron, the priest, saw this, he left the assembly, took a spear in his hand

8and followed the Israelite into the tent. He drove the spear into both of them, right through the Israelite man and into the woman’s stomach. Then the plague against the Israelites was stopped;

9but those who died in the plague numbered 24,000.
