Moses offered an alternative
Moses is given the opportunity to start fresh with just his descendants, but he begs for the Lord to not harm His people for their rebellion.
Numbers 14:11–12The Lexham English Bible
And Yahweh said to Moses, “How long until this people will despise me, and how long until they will not believe in me, and in all the signs that I have done in their midst? I will strike them with disease, and I will dispossess them; I will make you into a greater and stronger nation than them.”
