Numbers 25:3

Israel joined himself unto Baal-peor— See the note on ch. Numbers 21:29. St. Jerome informs us, that Baal-peor was the same as the Greek and Roman Priapus; that this idol was like that of Priapus. That his worship consisted of gross obscenity and impurity there can be no question. See Hosea 10:15 and Revelation 2:14. Those who are inclined to know more respecting this idol, (who, with his ceremonies, was of too gross a sort to engage our further attention,) may consult Calmet's Dissertation upon the subject. When it is said, Psalms 106:28 that they joined themselves unto Baal-peor, and ate the offerings of the dead, it cannot be concluded from thence that Baal-peor was some dead prince idolized; for the dead, in this place, means no more than those dead idols, whom St. Paul calls, nothing in the world, 1 Corinthians 8:4 and who may be denominated dead, in opposition to the living God. See Vossius, de Idol. lib. 2: cap. 7.
