Numbers 25:3

Israel joined himself unto Baal-peor - The same as the Priapus of the Romans, and worshipped with the same obscene rites as we have frequently had occasion to remark.

The joining to Baal-peor, mentioned here, was probably what St. Paul had in view when he said, 2 Corinthians 6:14 : Be ye not unequally yoked together with unbelievers. And this joining, though done even in a matrimonial way, was nevertheless fornication, (see Revelation 2:14), as no marriage between an Israelite and a Midianite could be legitimate, according to the law of God. See the propositions at the close of the preceding chapter Numbers 24:25 (note).

Joined himself - i. e., by taking part in the sacrificial meals as described in the last verse. Compare Exodus 34:15; 1 Corinthians 10:18. The worship of Baal was attended with the grossest impurity, and indeed partly consisted in it Hosea 4:14; Hosea 9:10.

Baal-peor - i. e., the Baal worshipped at Peer, the place mentioned in Numbers 23:28 (compare Baal-meon, Numbers 32:38). (The identification of this god with Chemosh in Numbers 21:29 is now given up.)

25:3 Joined himself - The word implies a forsaking God to whom they were joined and a turning to, and strict conjunction with, this false God.Baal - peor - Called Baal, by the name common to many false Gods, and especially to those that represented any of the heavenly bodies, and Peor, either from the hill Peor, where he was worshipped, Numbers 23:28 ,rather from a verb signifying to open and uncover, because of the obscene posture in which the idol was set, as Priapus was: or because of the filthiness which was exercised in his worship.
