“Therefore, say to the people of Israel: ‘I am the Lord. I will free you from your oppression and will rescue you from your slavery in Egypt. I will redeem you with a powerful arm and great acts of judgement. I will claim you as my own people, and I will be your God. Then you will know that I am the Lord you God who has freed you from you oppression in Egypt. I will bring you into the land I swore to Abraham, Issac, and Jacob. I will give it to you as your very own possession. I am the Lord!'”
Then the Lord told Moses “Go back to Pharaoh, the king of Egypt, and tell hi to let the people of Israel leave his country.”
“But, Lord!” Moses objected. “My own people won’t listen to me. How can I expect Pharaoh to listen: I am such a clumsy speaker!:
But the Lord spoke to Moses and Aaron and gave them the orders for the Israelites and for Pharaoh, the king of Egypt. The Lord commanded Moses and Aaron to lead the people of Israel out of Egypt. (vv. 6-13, NLT)
