John Wesley on Isaiah 65:25

The wolf, &c. - God here promises to take off the fierceness of the spirits of his peoples enemies, so that they shall live quietly and peaceably together. And dust - God promises a time of tranquility to his church under the metaphor of serpents eating the dust, their proper meat, Gen 3:14, instead of flying upon men: it signifies such a time, when wicked men shall no more eat up the people of God.
