Numbers 25:6-8

⁶ And behold, a man of the children of Israel came and brought a Midianitish woman to his brethren, in the sight of Moses, and in the sight of the whole assembly of the children of Israel, who were weeping before the entrance of the tent of meeting. ⁷ And Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, and rose up from among the assembly, and took a javelin in his hand, ⁸ and he went after the man of Israel into the tent-chamber, and thrust both of them through, the man of Israel and the woman through her belly. And the plague was stayed from the children of Israel.
