Exodus 4:4 YLT

²  And Jehovah saith unto him, 'What 'is' this in thy hand?' and he saith, 'A rod;'

³  and He saith, 'Cast it to the earth;' and he casteth it to the earth, and it becometh a serpent -- and Moses fleeth from its presence.

⁴  And Jehovah saith unto Moses, 'Put forth thy hand, and lay hold on the tail of it;' and he putteth forth his hand, and layeth hold on it, and it becometh a rod in his hand --

⁵  '-- so that they believe that Jehovah, God of their fathers, hath appeared unto thee, God of Abraham, God of Isaac, and God of Jacob.'

⁶  And Jehovah saith to him again, 'Put in, I pray thee, thy hand into thy bosom;' and he putteth in his hand into his bosom, and he bringeth it out, and lo, his hand 'is' leprous as snow;
