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 (Pirḳe R. El. 40; Sefer ha-Yashar; Yalḳ. Exodus 168, end). It must, however, be remarked that the Mishnah (Pirkei Avoth v. 9) as yet knew nothing of the miraculous creation of Aaron's Rod, which is first mentioned by the Mekilta (l.c.) and Sifre on Deuteronomy (Berakhot xxxiii. 21; ed. Friedmann, p. 355).
