Exodus 18:11

Now I know. This text is not easy to explain, and has been taken by some commentators as proof that Jethro was a polytheist. Jethro, however, was “the godly priest of Midian” (PP 301). Here, with the additional evidence recounted by Moses, Jethro simply reaffirms his faith in the true God. For in the thing. This statement is even less clear than the preceding one. The translators of the KJV apparently understood Jethro to say that God had shown Himself superior to the gods of Egypt. A more literal translation would read, “Even in the very matter that they [the Egyptians] dealt proudly against them [the Israelites].” Such a rendition sees the superiority of the Lord revealed in the way the pride of the Egyptians was humbled by the power of God (see on v. 10).
