John Wesley on Isaiah 64:4

Besides thee - This is to be applied to all the wonderful works, that God at all times wrought for his people: and thus they are a plea with God, that they might well expect such things from him now, that had done such wonderful things for their fathers. Waiteth - This may be taken with reference both to the state of grace and glory, those incomprehensible things that are exhibited through Christ in the mysteries of the gospel.
