Numbers 25:7-8

⁷And Phinehas bar Elazar bar Aharon the priest saw, and arose from the midst of the congregation, and took a lance in his hand;

⁸And he went in after the man, the son of Israel, into the tent, and thrust both of them through, the man, the son of Israel, and the woman, through her belly; and the pestilence was stayed from the children of Israel.
