Now I know, viz. more clearly and by certain experience; as that phrase signifies, Genesis 22:12 1 Kings 17:18,24. For otherwise it is more than probable that Jethro had the knowledge of the true God before this time, not only because he was the great-grandchild of Abraham, but also because of his long conversation with a person of so great knowledge, and wisdom, and piety, as Moses was. Wherein they dealt proudly; either,
1. Their false gods, who wrought strange things in and by their servants the magicians, who contended with Moses, and proudly boasted of their skill as not a whit inferior to that of Moses, but at last were forced to yield up the cause, Exodus 8:19; or rather,
2. The Egyptians, spoken of Exodus 18:10, who dealt proudly, and scornfully, and tyrannically with the Israelites, but God showed himself to be above them, and above their king; though Pharaoh would not own him for his superior, Exodus 5:2, but lift up his horn against God, and against his people: but the Lord brought that proud prince upon his knees, and forced him oft to confess his faults, and to become suppliant to Moses for deliverance from the plagues; and at last, when he continued incorrigible, he drowned him in the sea.
