Numbers 25:7-9

Young's Literal Translation

⁷ and Phinehas, son of Eleazar, son of Aaron, the priest, seeth, and riseth from the midst of the company, and taketh a javelin in his hand,

⁸ and goeth in after the man of Israel unto the hollow place, and pierceth them both, the man of Israel and the woman -- unto her belly, and the plague is restrained from the sons of Israel;

⁹ and the dead by the plague are four and twenty thousand.
