Exodus 7:5-7

Wycliffe Bible

⁵ and [the] Egyptians shall know, that I am the Lord, which have held forth mine hand on Egypt, and have led out of the midst of them the sons of Israel. (and then the Egyptians shall know, that I am the Lord, when I have stretched forth my hand against Egypt, and have led the Israelites out of their midst.)

⁶ And so Moses did and Aaron; as the Lord commanded, so they did. (And so Moses and Aaron did as the Lord commanded; yea, so they did.)

⁷ Forsooth Moses was of fourscore years, and Aaron of fourscore years and three, when they spake to Pharaoh.
