Commentary for Exodus 7:1

נתתיך אלהים לפרעה This signifies I have made thee a judge and castigator — to castigate him with plagues and pains.

נביאך, your spokesman.

ראה נתתיך אלוהים לפרעה, “see I have made you like a God as far as Pharaoh is concerned.” According to Ibn Ezra the word אלוהים here merely denotes that Moses had been elevated to a very high rank, so much so that Pharaoh would relate to him with the same reverence as he would display when facing a disembodied angel of G’d who addresses the prophet whereas the prophet subsequently relays the words of the angel to his people.
