Exodus 18:11 - Wesley's Explanatory Notes

Now know I that JEHOVAH is greater than all gods — That the God of Israel is greater than all pretenders; all deities, that usurp divine honours: he silenceth them, subdues them all, and is himself the only living and true God. He is also higher than all princes and potentates, who also are called gods, and has both an incontestable authority over them, and an irresistible power to control them; he manages them all as he pleaseth, and gets honour upon them how great soever they are. Now know I: he knew it before, but now he knew it better; his faith grew up to a full assurance, upon this fresh evidence; for wherein they dealt proudly — The magicians or idols of Egypt, or Pharaoh and his grandees, opposing God, and setting up in competition with him, he was above them. The magicians were baffled, Pharaoh humbled, his powers broken, and Israel rescued out of their hands.
