John Wesley on Exodus 3:8

I am come down to deliver them - When God doth something very extraordinary, he is said to come down to do it, as Isa 64:1. This deliverance was typical of our redemption by Christ, and in that the eternal Word did indeed come down from heaven to deliver us. A large land - So it was, according to its true and ancient bounds, as they are described, Gen 15:18, and not according to those narrow limits, to which they were afterwards confined for their unbelief and impiety. A land flowing with milk and honey - A proverbial expression, abounding with the choicest fruits, both for necessity and delight.
