III. That though they had been in continual troubles, as if the whole creation had been at war with them, now they shall enjoy perfect peace and tranquillity, as if they were in a league of friendship with the whole creation (v. 18): In that day, when they have forsaken their idols, and put themselves under the divine protection, I will make a covenant for them. 1. They shall be protected from evil; nothing shall hurt them, nor do them any mischief. Tranquillus Deus tranquillat amnia—When God is at peace with us he makes every creature to be so too. The inferior creatures shall do them no harm, as they had done when the beasts of the field ate up their vineyards (v. 12) and when noisome beasts were one of God's sore judgments, Ezek. xiv. 15. The fowl and the creeping things are taken into this covenant; for they also, when God makes use of them as the instruments of his justice, may be come very hurtful, but they shall be no more so; nay, by virtue of this covenant, they shall be made serviceable to them and brought into their interests. Note, God has the command of the inferior creatures, and brings them into what covenant he pleases; he can make the beasts of the field to honour him (so he has promised, Isa. xliii. 20) and to contribute to his people's comfort. And, if the inferior creatures are thus laid under an engagement to serve us, it is our part of the covenant not to abuse them, but to serve God with them. Some think that this had its accomplishment in the miraculous power Christ gave his disciples to take up serpents, Mark xvi. 17, 18. It agrees with the promises made particularly to Israel, in their return out of captivity (Ezek. xxxiv. 25, I will cause the evil beasts to cease out of the land), and the more general ones to all the saints. Job v. 22, 23, The beasts of the field shall be at peace with thee; and Ps. xci. 13, Thou shalt tread upon the lion and the adder. But this is not all; men are more in danger from one another than from the brute beast, and therefore it is further promised that God will make wars to cease, will disarm the enemy: I will break the bow, and sword, and battle. He can do it when he pleases (Ps. xliv. 9), and will do it for those whose ways please him, for he makes even their enemies to be at peace with them, Prov. xvi. 7. This agrees with the promise that in gospel-times swords shall be beaten into plough-shares, Isa. ii. 4. 2. They shall be quiet from the fear of evil. God will not only keep them safe, but make them to lie down safely, as those that know themselves to be under the protection of Heaven, and therefore are not afraid of the powers of hell.
