Reconciliation being made, a covenant of friendship is here settled between God and Israel. The traitors are not only pardoned, but preferred and made favourites again. Well may the assurances of this be ushered in with a behold, a word commanding attention and admiration: Behold, I make a covenant. When the covenant was broken, it was Israel that broke it; now that it comes to be renewed, it is God that makes it. If there be quarrels, we must bear all the blame; if there be peace, God must have all the glory. Here is,

I.God's part of this covenant, what he would do for them, Exo 34:10, Exo 34:11. 1. In general: Before all thy people, I will do marvels. Note, Covenant-blessings are marvellous things (Psa 98:1), marvels in the kingdom of grace; those mentioned here were marvels in the kingdom of nature, the drying up of Jordan, the standing still of the sun, etc. Marvels indeed, for they were without precedent, such as have not been done in all the earth. They were the joy of Israel, and the confirmation of their faith: Thy people shall see, and own the work of the Lord. And they were the terror of their enemies: It is a terrible thing that I will do. Nay, even God's own people should see them with astonishment. 2. In particular: I drive out before thee the Amorite. God, as King of nations, plucks up some, to plant others, as it pleases him; as King of saints, he made room for the vine he brought out of Egypt, Psa 80:8, Psa 80:9. Kingdoms are sacrificed to Israel's interests, Isa 43:3, Isa 43:4.

II.Their part of the covenant: Observe that which I command thee. We cannot expect the benefit of the promises unless we make conscience of the precepts.

1.The two great precepts are, (1.) Thou shalt worship no other gods (Exo 34:14), not give divine honour to any creature, or any name whatsoever, the creature of fancy. A good reason is annexed. It is at thy peril if thou do: For the Lord, whose name is Jealous, is a jealous God, as tender in the matters of his worship as the husband is of the honour of the marriage-bed. Jealousy is called the rage of a man (Pro 6:34), but it is God's holy and just displeasure. Those cannot worship God aright who do not worship him alone. (2.) "Thou shalt make thee no molten god (Exo 34:17); thou shalt not worship the true God by images." This was the sin they had lately fallen into, which therefore they are particularly cautioned against.

2.Fences are here erected about these two precepts by two others: (1.) That they might not be tempted to worship other gods, they must not join in affinity or friendship with those that did (Exo 34:12): "Take heed to thyself, for thou art upon thy good behaviour. It is a sin that thou art prone to and that will easily beset thee, and therefore be very cautious, and carefully abstain from all appearances of it and advances towards it. Make no covenant with the inhabitants of the land." If God, in kindness to them, drove out the Canaanites, they ought, in duty to God, not to harbour them. What could be insisted on more reasonable than this? If God make war with the Canaanites, let not Israel make peace with them. If God take care that the Canaanites be not their lords, let them take care that they be not their snares. It was for their civil interest to complete the conquest of the land; so much does God consult our benefit in the laws he gives us. They must particularly take heed of intermarrying with them, Exo 34:15, Exo 34:16. If they espoused their children, they would be in danger of espousing their gods; such is the corruption of nature that the bad are much more likely to debauch the good than the good to reform the bad. The way of sin is downhill: those that are in league with idolaters will come by degrees to be in love with idolatry; and those that are prevailed upon to eat of the idolatrous sacrifice will come at length to offer it. Obsta principiis - Nip the mischief in the bud. (2.) That they might not be tempted to make molten gods, they must utterly destroy those they found and all that belong to them, the altars and groves (Exo 34:13), lest, if these were left standing, they should be brought, in process of time, either to use them or to take pattern by them, or to abate in their detestation and dread of idolatry. The relics of idolatry ought to be abolished as affronts to the holy God and a great reproach to human nature. Let it never be said that men who pretend to reason were ever guilty of such absurdities as to make gods of their own and worship them.

I will do marvels - This seems to refer to what God did in putting them in possession of the land of Canaan, causing the walls of Jericho to fall down; making the sun and moon to stand still, etc. And thus God made his covenant with them; binding himself to put them in possession of the promised land, and binding them to observe the precepts laid down in the following verses, from Exodus 34:11-26 inclusive.

Take heed to thyself,.... This is said not to Moses, but to the people of Israel, as a caution to them when they should enter the land of Canaan, and possess it:

lest thou make a covenant with the inhabitants of the land whither thou goest: enter into a league and alliance, to live friendly and amicably, and support and assist each other against the common enemy; whereas they were to smite the seven nations and destroy them, and show them no mercy, Deu 7:1.

lest it be for a snare in the midst of thee; be the means of drawing them into the same sinful practices with themselves, especially into idolatrous ones, and so of bringing ruin and destruction on them.

he said, If now I have found grace in thy sight, O Lord, let my Lord, I pray thee, go among us--On this proclamation, he, in the overflowing benevolence of s heart, founded an earnest petition for the Divine Presence being continued with the people; and God was pleased to give His favorable answer to Moses' intercession by a renewal of His promise under the form of a covenant, repeating the leading points that formed the conditions of the former national compact.
