Exodus 7:1-7

1The Lord answered Moses, “I have made you a god to Pharaoh, and your brother Aaron is your prophet.

2Tell your brother Aaron everything I command you, and he must tell Pharaoh to let the Israelites leave the country.

3But I will make Pharaoh stubborn. Even though I will do many miraculous signs and amazing things in Egypt,

4Pharaoh will not listen to you. Then I will use my power to punish Egypt severely, and I will bring my people, the Israelites, out of Egypt in organized family groups.

5The Egyptians will know that I am the Lord when I use my power against Egypt and bring the Israelites out of there.”

6Moses and Aaron did as the Lord had commanded them.

7Moses was 80 years old and Aaron was 83 when they talked to Pharaoh.
