Let me alone, that I may destroy them,.... Do not say one word to me on their behalf, or entreat me to spare them, and not destroy them: and blot out their name from under heaven; that no such nation may be heard of, or known by the name of Israel: and I will make of thee a nation mightier and greater than they; of his family, whereby the Lord's promise to Abraham would not have been made void, but equally firm and sure, since this mightier and greater nation would have been of his seed; See Gill on Exo 32:10.
