Numbers 25:7-9

Wycliffe Bible

⁷ And when Phinehas, the son of Eleazar, the son of Aaron, the priest, had seen this unshamefast doing (had seen this shameful thing), he rose (up) from the midst of the multitude; and when he had taken a sword,

⁸ he entered after the man of Israel into the whorehouse, and sticked through both together, that is, the man and the woman, in the places of engendering. And the vengeance ceased from the sons of Israel, (he went into that bawdy house, after the man of Israel, and stuck his sword through both of them together, that is, the man and the woman, in their places of begetting. And so the plague that had attacked the Israelites was stopped,)

⁹ and four and twenty thousand of men were slain. (but by then, twenty-four thousand people had already died.)
