AARON'S ROD — a rod mentioned on two dramatic occasions in the Old Testament. When Moses and Aaron appeared before Pharaoh, Aaron cast down his rod and it became a serpent. When the magicians of Egypt did the same thing, “Aaron's rod swallowed up their rods” (Ex. 7:12). Later, Aaron struck the waters of Egypt with his rod and they turned to blood (7:15–20).

During the wilderness wandering, Aaron's rod was the only staff that produced buds, blossoms, and almonds, indicating God's choice of Aaron and his descendants as priests (Num. 17:1–10).
