The Lord said, "I am going to make you like God to the king, and your brother Aaron will speak to him as your prophet.
Tell Aaron everything I command you, and he will tell the king to let the Israelites leave his country.
But I will make the king stubborn, and he will not listen to you, no matter how many terrifying things I do in Egypt. Then I will bring severe punishment on Egypt and lead the tribes of my people out of the land. 15
The Egyptians will then know that I am the Lord, when I raise my hand against them and bring the Israelites out of their country."
Moses and Aaron did what the Lord commanded.
