Exodus 4:1-7

1 And Moses answered and said, But, behold, they will not believe me, nor hearken unto my voice; for they will say, Jehovah hath not appeared unto thee.
2 And Jehovah said unto him, What is that in thy hand? And he said, A rod.
3 And he said, Cast in on the ground. And he cast it on the ground, and it became a serpent; and Moses fled from before it.
4 And Jehovah said unto Moses, Put forth thy hand, and take it by the tail: (and he put forth his hand, and laid hold of it, and it became a rod in his hand:)
5 That they may believe that Jehovah, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee.
6 And Jehovah said furthermore unto him, Put now thy hand into thy bosom. And he put his hand into his bosom: and when he took it out, behold, his hand was leprous, as [white as] snow.
7 And he said, Put thy hand into thy bosom again. (And he put his hand into his bosom again; and when he took it out of his bosom, behold, it was turned again as his [other] flesh.)
