Exodus 7
v.1
Then the LORD said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet.
While the Lord had made Moses as “God” to Aaron and Aaron in turn as his “prophet” (GK 5566) to the people, Moses was also ordained as “God” to Pharoah in that he would speak and act with authority and power from above and Aaron would be Moses’ “prophet” addressing Pharoah (cf. 4:15-16).
v.5
And the Egyptians will know that I am the LORD when I stretch out my hand against Egypt and bring the Israelites out of it.”
v.11
Pharaoh then summoned wise men and sorcerers, and the Egyptian magicians also did the same things by their secret arts:
v.16
Then say to him, ‘The LORD, the God of the Hebrews, has sent me to say to you: Let my people go, so that they may worship me in the desert. But until now you have not listened.
v.22
But the Egyptian magicians did the same things by their secret arts, and Pharaoh’s heart became hard; he would not listen to Moses and Aaron, just as the LORD had said.
