Exodus 3:9-11 (NKJV)

Now therefore, behold, the cry of the children of Israel has come to Me, and I have also seen the oppression with which the Egyptians oppress them. 

10 Come now, therefore, and I will send you to Pharaoh that you may bring My people, the children of Israel, out of Egypt.”

11 But Moses said to God, “Who am I that I should go to Pharaoh, and that I should bring the children of Israel out of Egypt?”
