Moses shall stand before Pharaoh like God.
What does this mean?
He will speak on behalf of God; his message is God’s message. This is similar to when an angel speaks on behalf of God, as in Exodus 3:2, when the angel of the Lord appears to Moses, and in Exodus 3:4 we are told that God called to him out of the bush.
Who is the angel of the Lord
in Exodus 3:2?
Moses is a representative of God, and acts on God’s behalf.
He is as a god
for the Pharaoh, who is revered as a god. The Pharaoh sees himself as more than a human (a god incarnate), but Moses is his equal.
Moses is a god who speaks, not as the idols who have a mouth but can not speak (Psalm 135:16). Aaron is his speaker, his prophet. Moses, as a prophet of God, is now, himself as a god,
with Aaron as his prophet.
Moses is a unique prophet (see Numbers 12:6–8). In Numbers 12:2, Aaron and Miriam set themselves up as equal to Moses, and it displeases God (see Numbers 12:9).
1 And the LORD said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron shall be your prophet.
