Exodus 7:4-6 New English Translation (NET Bible)
4 Pharaoh will not listen to you. I will reach into Egypt and bring out my regiments, my people the Israelites, from the land of Egypt with great acts of judgment. 5 Then the Egyptians will know that I am the Lord, when I extend my hand over Egypt and bring the Israelites out from among them.
6 And Moses and Aaron did so; they did just as the Lord commanded them.
