Êxodo 4

6 Then the Lord said to him again, Put your hand inside your clothing. And he put his hand inside his robe: and when he took it out it was like the hand of a leper, as white as snow.

7 And he said, Put your hand inside your robe again. (And he put his hand into his robe again, and when he took it out he saw that it had become like his other flesh.)
