Exo 4:2 | KD | STEP | The First Sign. - The turning of Moses’ staff into a serpent, which became a staff again when Moses took it by the tail, had reference to the calling of Moses. The staff in his hand was his shepherd’s crook (מזּה , for מה־זה, in this place alone), and represented his calling as a shepherd. At the bidding of God he threw it upon the ground, and the staff became a serpent, before which Moses fled. The giving up of his shepherd-life would expose him to dangers, from which he would desire to escape. At the same time, there was more implied in the figure of a serpent than danger which merely threatened his life. The serpent had been the constant enemy of the seed of the woman (Gen 3), and represented the power of the wicked one which prevailed in Egypt. The explanation in Pirke Elieser , c. 40, points to this: ideo Deum hoc signum Mosi ostendisse, quia sicut serpens mordet et morte afficit homines, ita quoque Pharao et Aegyptii mordebant et necabant Israelitas . But at the bidding of God, Moses seized the serpent by the tail, and received his staff again as “the rod of God,” with which he smote Egypt with great plagues. From this sign the people of Israel would necessarily perceive, that Jehovah had not only called Moses to be the leader of Israel, but had endowed him with the power to overcome the serpent-like cunning and the might of Egypt; in other words, they would “believe that Jehovah , the God of the fathers, had appeared to him.” (On the special meaning of this sign for Pharaoh, see Exo 7:10.)
