27. They were the ones who spoke to Pharaoh king of Egypt about bringing the Israelites out of Egypt – this same Moses and Aaron.

28. Now when the Lord spoke to Moses in Egypt,

29. he said to him, ‘I am the Lord. Tell Pharaoh king of Egypt everything I tell you.’

30. But Moses said to the Lord, ‘Since I speak with faltering lips, why would Pharaoh listen to me?’
