Numbers 25:5-8

Thomson(i) 5 Then Moses said to the tribes of Israel, Kill ye, every one, him of his family, who hath consecrated himself to Belphegor. 6 And behold there came a man of the children of Israel, who conducted his brother to a Madianitish woman in the sight of Moses, and before all the congregation of the sons of Israel, while they were weeping at the door of the tabernacle of the testimony. 7 Upon seeing this, Phineas, son of Eleazar, son of Aaron the priest, started up from among the congregation, and taking a javelin in his hand, 8 went after the man; the Israelite, into the bed chamber, and ran them both through, the man, the Israelite, quite through, and the woman into her belly. Whereupon the plague stopped from the children of Israel.
