Êxodo 3

10 and now, come, and I send thee unto Pharaoh, and bring thou out My people, the sons of Israel, out of Egypt.’

11 And Moses saith unto God, ‘Who [am] I, that I go unto Pharaoh, and that I bring out the sons of Israel from Egypt?’

12 and He saith, ‘Because I am with thee, and this [is] to thee the sign that I have sent thee: in thy bringing out the people from Egypt — ye do serve God on this mount.’
