Shemot 4:1-3

Orthodox Jewish Bible

4 And Moshe answered and said, But, what if they will not believe me, nor pay heed unto my voice but will say, Hashem hath not appeared unto thee.

² And Hashem said unto him, What is that in thine yad? And he said, A matteh (a rod, staff).

³ And He said, Cast it on the ground. And he cast it on the ground, and it became a nachash; and Moshe fled from before it.
