אלשיך — והמטה אשר נהפך לנחש תקח בידך

Q — Why, when sending Moshe to confront Pharaoh by the river, does Hashem reference the staff that turned into a *snake* — the original sign at the burning bush — rather than the staff-into-תנין sign that has just been performed for Pharaoh?

A — Because the three-stage staff sign was always a coded parable about Moshe and Pharaoh themselves. When Moshe was growing up in the palace ('המטה ביד משה'), Pharaoh was harmless — a staff in his hand. When Moshe withdrew ('ויגדל משה ויצא אל אחיו'), the staff became a serpent and Pharaoh sought to kill him; Moshe fled to Midyan. The lesson Hashem is reminding him: 'בשלחך יד לאחוז בו... לשים פניך נגדו בכח בלי פחד, יהי למטה בכפך כעץ דומם.' Confront Pharaoh head-on, by the river where he goes in shame to relieve himself, with no fear — and he reverts to a powerless stick.
