Rabbinic
midrash described attributes of Aaron's rod beyond those in the Biblical text. It is reported that the rod was made of
sapphire, weighed forty seahs (a seah = 10.70 pounds), and bore the inscription דצ״ך עד״ש באח״ב (the initials of the
Hebrew names of the
Ten Plagues). God created it in the twilight of the sixth day of Creation, and delivered it to
Adam when the latter was driven from paradise. After it had passed through the hands of
Shem,
Enoch,
Abraham,
Isaac, and
Jacob successively, it came into the possession of
Joseph. On Joseph's death the Egyptian nobles stole some of his belongings, and, among them,
Jethro appropriated the staff. Jethro planted the staff in his garden, when its marvelous virtue was revealed by the fact that nobody could withdraw it from the ground (compare "
the sword in the stone"); even to touch it was fraught with danger to life. This was because the Ineffable Name of God was engraved upon it. When Moses entered Jethro's household he read the Name, and by means of it was able to draw up the rod, for which service
Zipporah, Jethro's daughter, was given to him in marriage. Her father had sworn that she should become the wife of the man who should be able to master the miraculous rod and of no other. Aaron's rod, together with its blossoms and fruit, was preserved in the Ark. King
Josiah, who foresaw the impending national catastrophe, concealed the Ark and the objects stored with it (Aaron's rod, a vial of
manna, and the
holy anointing oil). Their whereabouts will remain unknown until, in the Messianic age, the prophet Elijah shall reveal them. According to one midrash, Moses split a tree trunk into twelve portions, and gave one portion to each tribe. When the Rod of Aaron produced blossoms, the Israelites could not but acknowledge the significance of the token. This opinion seemingly assumes that the rod in Korach's rebellion was separate from the rod used for the plagues. ==Christian use==
