Numbers 25:10

7 When Phinehas, the son of Eleazar, the son of Aaron the priest, saw it, he rose up from the middle of the congregation, and took a spear in his hand.

8 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 body. So the plague was stopped among the children of Israel.

9 Those who died by the plague were twenty-four thousand.

10 The LORD spoke to Moses, saying,

11 “Phinehas, the son of Eleazar, the son of Aaron the priest, has turned my wrath away from the children of Israel, in that he was jealous with my jealousy among them, so that I didn’t consume the children of Israel in my jealousy.

12 Therefore say, ‘Behold, I give to him my covenant of peace.

13 It shall be to him, and to his offspring after him, the covenant of an everlasting priesthood, because he was jealous for his God, and made atonement for the children of Israel.’”
