v 3 and 4 ... He threw it (his rod) on the ground, and it became a snake ... He stretched out his hand, and took hold of it, and it became a rod in his hand.
and v 6 and 7 ... He put his hand inside his cloak, and when he took it out, behold, his hand was leprous, as white as snow ... He put his hand inside his cloak again, and when he took it out of his cloak, behold, it had turned again as his other flesh.
