Numbers 25:5, 7-12

So Moses told Israel’s judges, “Kill each of the men who aligned themselves with Baal of Peor.”

When Phinehas son of Eleazar, son of Aaron the priest, saw this, he got up from the assembly, took a spear in his hand, followed the Israelite man into the tent,  and drove it through both the Israelite man and the woman — through her belly. Then the plague on the Israelites was stopped, but those who died in the plague numbered twenty-four thousand.  The LORD spoke to Moses, “Phinehas son of Eleazar, son of Aaron the priest, has turned back my wrath from the Israelites because he was zealous among them with my zeal,  , so that I did not destroy the Israelites in my zeal. Therefore declare: I grant him my covenant of peace.
