Exodus 6:9-13

9Moses told the Lord's message to the Israelites. But they refused to listen to him. They were very weak and tired, because their Egyptian masters were so cruel to them.

10Then the Lord said to Moses,

11‘Go and speak to Pharaoh, king of Egypt. Tell him that he must let the Israelites go out of his country.’

12But Moses said to the Lord, ‘Look! Even the Israelites have not listened to me. So Pharaoh certainly will not listen to me. You know that I do not speak well.’

13Then the Lord spoke to Moses and Aaron about the Israelites, and about Pharaoh, the king of Egypt. He commanded Moses and Aaron to lead the Israelites out of Egypt.
