Numbers 25:7

3 So Israel joined in worshiping Baal of Peor, and the anger of the LORD burned against them.

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

5 So Moses told the judges of Israel, “Each of you must kill all of his men who have joined in worshiping Baal of Peor.”

6 Just then an Israelite man brought to his family a Midianite woman in the sight of Moses and the whole congregation of Israel while they were weeping at the entrance to the Tent of Meeting.

7 On seeing this, Phinehas son of Eleazar, the son of Aaron the priest, got up from the assembly, took a spear in his hand,

8 followed the Israelite into his tent, and drove the spear through both of them—through the Israelite and on through the belly of the woman. So the plague against the Israelites was halted,

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

10 Then the LORD said to Moses,

11 “Phinehas son of Eleazar, the son of Aaron the priest, has turned My wrath away from the Israelites; for he was zealous for My sake among them, so that I did not consume the Israelites in My zeal.
