Exodus 6:9-13

9So Moses told the people of Israel what the Lord had said, but they refused to listen anymore. They had become too discouraged by the brutality of their slavery.

10Then the Lord said to Moses,

11“Go back to Pharaoh, the king of Egypt, and tell him to let the people of Israel leave his country.”

12“But Lord!” Moses objected. “My own people won’t listen to me anymore. How can I expect Pharaoh to listen? I’m such a clumsy speaker!”

13But the Lord spoke to Moses and Aaron and gave them 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.
