Exodus 18:9-11

Verse 9

And Jethro rejoiced for all the goodness - Every part of Jethro's conduct proves him to have been a religious man and a true believer. His thanksgiving to Jehovah (Exo 18:10) is a striking proof of it; he first blesses God for the preservation of Moses, and next for the deliverance of the people from their bondage.
Verse 11

Now I know that the Lord is greater than all gods - Some think that Jethro was now converted to the true God; but it is very probable that he enjoyed this blessing before he knew any thing of Moses, for it is not likely that Moses would have entered into an alliance with this family had they been heathens. Jethro no doubt had the true patriarchal religion.

Wherein they dealt proudly - Acting as tyrants over the people of God; enslaving them in the most unprincipled manner, and still purposing more tyrannical acts. He was above them - he showed himself to be infinitely superior to all their gods, by the miracles which he wrought. Various translations have been given of this clause; the above I believe to be the sense.
