Exodus 7:5-7

Modern English Version

⁵ And the Egyptians shall know that I am the Lord when I stretch forth My hand upon Egypt and bring out the children of Israel from among them.”

⁶ So Moses and Aaron did it. Just as the Lord commanded them, so they did. ⁷ Moses was eighty years old, and Aaron was eighty-three years old when they spoke to Pharaoh.
