Exodus 34:12

God having in the foregoing chapter intimated to Moses his reconciliation to Israel, here gives proofs of it, proceeding to settle his covenant and communion with them. Four instances of the return of his favour we have in this chapter: - I. The orders he gives to Moses to come up to the mount, the next morning, and bring two tables of stone with him (Exo 34:1-4). II. His meeting him there, and the proclamation of his name (Exo 34:5-9). III. The instructions he gave him there, and his converse with him for forty days together, without intermission (v. 10-28). IV. The honour he put upon him when he sent him down with his face shining (Exo 34:29-35). In all this God dealt with Moses as a public person, and mediator between him and Israel, and a type of the great Mediator.

34:12-17 Worship of idols was prohibited, particularly the idols of the peoples into whose lands the Israelites were going. Central to this restriction was the prohibition of treaties, or covenants, with these idol-worshiping peoples. Not only would the making of a treaty involve recognizing those peoples’ gods (because ancient treaties would call upon the gods as witnesses; see study note on 20:1–23:33), but the very existence of the treaties would predispose the Israelites to accept the ways of their treaty partners (34:12, 15-16).
