אור החיים — ראה נתתיך אלהים לפרעה

Q — At the end of Bo, Moshe accepts Pharaoh's banishment, declaring 'I will not see your face again' (לא אוסיף עוד ראות פניך). But how could Moshe commit to this — what if God should command him to return to Pharaoh? On whose authority did he speak?

A — Or HaChaim raises this difficulty in Vaera and resolves it through the framework God laid out before the plagues began: God told Moshe 'I have made you a god to Pharaoh, and Aharon your brother will be your prophet,' and foretold the full sequence ending with the Exodus. Knowing the divinely-ordained script of the confrontation, Moshe could speak with confidence that no further audience with Pharaoh would be required — his declaration matched what God had already revealed would unfold.
