Exodus 3:9-12

So because the Israelites’ cry for help has come to me, and I have also seen the way the Egyptians are oppressing them, therefore, go. I am sending you to Pharaoh so that you may lead my people, the Israelites, out of Egypt.” But Moses asked God, “Who am I that I should go to Pharaoh and that I should bring the Israelites out of Egypt?” He answered, “I will certainly be with you, and this will be the sign to you that I am the one who sent you: when you bring the people out of Egypt, you will all worship God at this mountain.”
