4. And the LORD said unto Moses, Put forth thine 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 the LORD, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath appeared unto thee.
6. And the LORD said furthermore unto him, Put now thine 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.
