NUMBERS 25:7-8

⁷And when Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from the midst of the congregation, and took a spear in his hand;

⁸and he went after the man of Israel into the pavilion, and thrust both of them through, the man of Israel, and the woman through her belly. So the plague was stayed from the children of Israel.
