the sense is, the Lord here promises this unto them, and that it shall be as sure and firm, and to be as much depended upon, as if it was established and settled by covenant, and should be enjoyed as a covenant mercy and blessing; and the creatures should as strictly observe it, and answer to it, as if bound by covenant: and this should reach not only to the beasts of the field, the wild beasts of prey, "but the fowls of heaven"; as the locusts and others, as Kimchi observes, which should not eat up the fruits and increase of the earth: "and the creeping things of the ground": as serpents and scorpions, as the same writer suggests.
Some think this was fulfilled in the first times of the Gospel, when the apostles took up serpents, and trod on scorpions, without any hurt; but then nothing was more common than for the Christians to be thrown to the lions, and devoured by beasts of prey.
Others refer it to the last days, the times of the restitution of all things, when they suppose all creatures will be restored to their paradisiacal estate, and be in entire subjection to men. Rather the sense is, that whereas noisome beasts, and other things, were one of God's sore judgments, with which he threatened his people, when they sinned against him, now they should no more be hurt by them in a way of judgment; and, indeed, should cease from being among them, so that they should be in no fear of them any more; see Le 26:22.
Though the words may be understood figuratively and mystically, either of deliverance from all spiritual enemies by Christ, as sin, Satan, and the world, and all others; or of freedom from all wicked men, cruel and crafty ones, open and secret persecutors of the saints: persecution will cease at the time of the Jews' conversion; antichrist, and all the antichristian states, will be destroyed; the beast and false prophet will be taken and cast into the furnace of fire; the old serpent, the devil, will be bound, during the Millennium; and there will be none to hurt in God's holy mountain, neither in the spiritual nor personal reign of Christ.
