Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

To recall the duties of the covenant once more to the minds of the people, the Lord repeats from among the rights of Israel, upon the basis of which the covenant had been established (ch. 21-23), two of the leading points which determined the attitude of the nation towards Him, and which constituted, as it were, the main pillars that were to support the covenant about to be renewed. These were, first, the warning against every kind of league with the Canaanites, who were to be driven out before the Israelites (Exo 34:11-16); and, secondly, the instructions concerning the true worship of Jehovah (Exo 34:17-26). The warning against friendship with the idolatrous Canaanites (Exo 34:11-16) is more fully developed and more strongly enforced than in Exo 23:23. The Israelites, when received into the covenant with Jehovah, were not only to beware of forming any covenant with the inhabitants of Canaan (cf. Exo 23:32-33), but were to destroy all the signs of their idolatrous worship, such as altars, monuments (see Exo 23:24), and asherim, the idols of Astarte, the Canaanitish goddess of nature, which consisted for the most part of wooden pillars (see my Comm. on Kg1 14:23), and to worship no other god, because Jehovah was called jealous, i.e., had revealed Himself as jealous (see at Exo 20:5), and was a jealous God. This was commanded, that the Israelites might not suffer themselves to be led astray by such an alliance; to go a whoring after their gods, and sacrifice to them, to take part in their sacrificial festivals, or to marry their sons to the daughters of the Canaanites, by whom they would be persuaded to join in the worship of idols. The use of the expression "go a whoring" in a spiritual sense, in relation to idolatry, is to be accounted for on the ground, that the religious fellowship of Israel with Jehovah was a covenant resembling the marriage tie; and we meet with it for the first time, here, immediately after the formation of this covenant between Israel and Jehovah. The phrase is all the more expressive on account of the literal prostitution that was frequently associated with the worship of Baal and Astarte (cf. Lev 17:7; Lev 20:5-6; Num 14:33, etc.). We may see from Num 25:1. how Israel was led astray by this temptation in the wilderness.
