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, Exod. 34:10, 11. 1. In general: Before all thy people, I will do marvels. Note, Covenant-blessings are marvellous things (Ps. 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, Ps. 80:8, 9. Kingdoms are sacrificed to Israel’s interests, Isa. 43:3, 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 (Exod. 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 (Prov. 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 (Exod. 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 (Exod. 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, Exod. 34:15, 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 (Exod. 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.
