Who is the Lord - Who is Jehovah, that I should obey his voice? What claims has he on me? I am under no obligation to him. Pharaoh spoke here under the common persuasion that every place and people had a tutelary deity, and he supposed that this Jehovah might be the tutelary deity of the Israelites, to whom he, as an Egyptian, could be under no kind of obligation. It is not judicious to bring this question as a proof that Pharaoh was an atheist: of this the text affords no evidence.
