“And the LORD said unto Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet.”
King James Version (KJV)
7:1 I have made thee a god to Pharaoh - That is, my representative in this affair, as magistrates are called gods, because they are God's vicegerents. He was authorized to speak and act in God's name, and endued with a divine power, to do that which is above the ordinary course of nature. And Aaron shall be thy prophet - That is, he shall speak from thee to Pharaoh, as prophets do from God to the children of men. Thou shalt as a god inflict and remove the plagues, and Aaron as a prophet shall denounce them.
