Exodus 3:9-12

I have heard the cries of the people of Israel, and I have seen the way the Egyptians have made life hard for them. So now I am sending you to the king of Egypt. Go! Bring my people, the Israelites, out of Egypt!” But Moses said to God, “I am not a great man! How can I go to the king and lead the Israelites out of Egypt?” God said, “I will be with you. This will be the proof that I am sending you: After you lead the people out of Egypt, all of you will worship me on this mountain.”
