Commentary for Exodus 5:22

למה הרעתה לעם הזה WHEREFORE HAST THOU DONE SO EVIL TO THIS PEOPLE? — And if You ask, “What concern is that of yours?” I answer “I have to complain that You have sent me at all” (Exodus Rabbah 5:22).

ADO-NOY’, WHEREFORE HAST THOU DEALT ILL WITH THIS PEOPLE? The Divine Name is here written Aleph Dalet, for through the Proper Name of G-d, [i.e., the Tetragrammaton], which is the attribute of mercy, no evil would befall the people. However, above [in Chapter 4, Verses 10 and 13], Moses twice mentioned the Divine Name written Aleph Dalet — [Bi Ado-noy (O G-d)] — since he was praying that the anger of G-d would not be kindled against him [for refusing to undertake the mission to go to Pharaoh]. Perhaps Moses was afraid to mention the Great Divine Name that was then being revealed to him and speaking to him.

וישב משה אל, he returned to the spot where G’d had been speaking to him previously.
