פּירוש אויף שמות 7:1

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

ראה נתתיך אלהים, “see that I have made you a G–d relative to him.” Since Pharaoh had proclaimed himself as the owner and therefore the god of the river Nile, G–d now appointed Moses as Pharaoh’s G–d, i.e. superpower.

נביאך, your spokesman.

יהיה נביאך [AARON] SHALL BE THY PROPHET — This must be understood as the Targum takes it: thy interpreter. Similarly, wherever this term of נבואה is mentioned it refers to a man who publicly proclaims and utters to the people words of reproof. It is of the same derivation as, (Isaiah 57:19) “utterance (ניב) of the lips”; (Proverbs 10:31) “it utters (ינוב) wisdom”; (I Samuel 10:13) “he made an end of proclaiming (התנבות)”, which is in the book of Samuel. In old French we call him predicar; English preacher.
