Exodus 4:16
Exodus 4:1616He will speak to the people for you. He will be your spokesman, and it will be as if you were God to him.
, where Jehovah tells Moses "he will serve as a mouth to you, and you will serve as God to him," is cited by JWs (together with ) to show that the word "god" applies to beings other than Jehovah in a non-divine sense. On that reading, Jesus being "a god" (NWT ) is just one more example of the flexible use.
Read carefully. Jehovah explains the function of the Moses-Aaron relationship: Aaron speaks for Moses as Moses speaks for God. The "as God to him" language describes a prophetic communication chain — Moses delivers divine words, Aaron relays them to the people — not a statement about Moses's nature. supplies the qualifier explicitly: "like God to Pharaoh" (NWT) — the word like makes it a simile, and "to Pharaoh" limits the scope to one audience. Moses never received worship, never created anything, never forgave sins on his own authority. Jesus does all three: created all things (, ), receives the worship of angels by divine command (), and forgives sins (). The Moses-god parallel is precisely the category that cannot accommodate Jesus — he exceeds it in every direction.
