Exodus 4:4 WBT

²  And the LORD said to him, What [is] that in thy hand? And he said, A rod.

³  And he said, Cast it on the ground. And he cast it on the ground, and it became a serpent: and Moses fled from before it.

⁴  And the LORD said to Moses, Put forth thy hand, and take it by the tail. And he put forth his hand, and caught it, and it became a rod in his hand:

⁵  That they may believe that the LORD God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared to thee.

⁶  And the LORD said furthermore to 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 snow.
