Staff of Moses
According to the Book of Exodus in the Bible, the staff used by Moses (called a rod in the King James Bible) was by his side throughout important milestones in the narrative. Amongst these milestone events or "miracles of the exodus" the Bible describes that the staff was used to produce water from a rock, was transformed into a snake and back, and was used at the parting of the Red Sea. Whether or not Moses' staff was the same as that used by his brother Aaron (known as Aaron's rod) has been debated by rabbinical scholars.
References to the staff
The staff is first mentioned in the Book of Exodus (chapter 4, verse 2), when God appears to Moses in the burning bush. God asks what Moses has in his hand, and Moses answers "a staff" (in the KJV version). The staff is miraculously transformed into a snake and then back into a staff. The staff is thereafter referred to as the "rod of God" or "staff of God" (depending on the translation).
"And thou shalt take this rod in thine hand, wherewith thou shalt do signs". And Moses went and returned to Jethro his father in law, and said unto him, "Let me go, I pray thee, and return unto my brethren which are in Egypt, and see whether they be yet alive". And Jethro said to Moses, "Go in peace". And the LORD said unto Moses in Midian, "Go, return into Egypt: for all the men are dead which sought thy life". And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: and Moses took the rod of God in his hand. (KJV. Exodus chap. 4)
Moses and Aaron appear before the pharaoh when Aaron's rod is transformed into a serpent. The pharaoh's sorcerers are also able to transform their own rods into serpents, but Aaron's swallows them. Aaron's rod is again used to turn the Nile blood-red. It is used several times on God's command to initiate the plagues of Egypt.
During the Exodus, Moses stretches out his hand with the staff to part the Red Sea. While in the "wilderness" after leaving Egypt Moses follows God's command to strike a rock with the rod to create a spring for the Israelites to drink from. But Moses strikes the rock twice with the staff when the water does not immediately appear after the first strike. For striking the rock twice, implying lack of faith, God punished Moses by not letting him enter into the promised land (Numbers 20:12).
Finally, Moses uses the staff in the battle at Rephidim between the Israelites and the Amalekites. When he holds up the "rod of God" the Israelites "prevail", when he drops it their enemies gain the upper hand. Aaron and Hur help him to keep the staff raised until victory is achieved.
Relation to Aaron's rod
Because Aaron's rod and Moses' rod are both given similar, seemingly interchangeable, powers, Rabbinical scholars debated whether or not the two rods were one and the same. According to the Midrash Yelammedenu (Yalḳ. on Ps. ex. § 869):
the staff with which Jacob crossed the Jordan is identical with that which Judah gave to his daughter-in-law, Tamar (Gen. xxxii. 10, xxxviii. 18). It is likewise the holy rod with which Moses worked (Ex. iv. 20, 21), with which Aaron performed wonders before Pharaoh (Ex. vii. 10), and with which, finally, David slew the giant Goliath (I Sam. xvii. 40). David left it to his descendants, and the Davidic kings used it as a scepter until the destruction of the Temple, when it miraculously disappeared. When the Messiah comes it will be given to him for a scepter in token of his authority over the heathen.
In later Jewish legend the rod was said to have been created at the beginning of the world on the sixth day of creation and to have been passed down through the hands of the major patriarchs before being inherited by Moses.
There are many speculations about what has happened to Moses's staff.
The Midrash (a homiletic method of biblical exegesis) states that the staff was passed down from generation to generation and was in the possession of the Judean kings until the First Temple was destroyed. It is unknown what became of the staff after the Temple was destroyed and the Jews were exiled from the land.
According to an identifying document at the Hagia Sophia in Istanbul, Moses's staff is on display today at the Topkapı Palace, Istanbul, Turkey. The Topkapi Palace holds other reputedly holy relics, most notably of the Prophet Muhammad. (Such as his bow, his sword, his footprint, and even a tooth.) Topkapı Palace was officially designated a museum in 1924, and the holy relics were placed on public view on 31 August 1962. It is said that Sultan Selim I (1512–1520) brought the holy relics to Topkapi Palace after conquering Egypt in 1517. These holy relics were used every year for ceremonial purposes: On the fifteenth day of the month of Ramazan several of the items were kissed by the Sultan, his vezirs and dignitaries. This was believed to bring about the victory of good and the defeat of evil, during the reign of Sultan Selim.
