Israel looked at the staff of Moses and saw only devastation. It had brought ten plagues upon the Egyptians in Egypt — blood, frogs, lice, and all the rest. Then it brought ten more plagues upon them at the sea, splitting the waters and drowning Pharaoh's entire army. Twenty catastrophes delivered by a single piece of wood. The people concluded that the staff was an instrument of punishment, nothing more.

God intended to overturn that assumption. "Take your staff with which you smote the Nile," He told Moses (Exodus 17:5), "and go." But this time, the staff would not bring destruction. It would strike a rock in the desert and produce water for a thirsty nation. The same rod that had turned the Nile to blood would now quench Israel's thirst.

The Mekhilta explains that God deliberately chose this instrument because of the people's "murmurings." They had complained that sacred objects only brought harm. So God proved them wrong using the most feared object of all. If even the staff of plagues could perform acts of mercy, then nothing in creation was locked into a single purpose.

This teaching parallels the lessons about the incense and the Ark. All three were feared. All three were redeemed. The pattern is consistent: what terrifies you today may save you tomorrow. God's instruments serve His purposes, and His purposes are not limited to judgment.
