Exodus 4, 6 – 9 „Again the LORD said to him: Put your hand into the fold of your garment. So he put his hand into the fold of his garment, and when he drew it out, there was his hand covered with scales, like snowflakes. 7Then God said: Put your hand back into the fold of your garment. So he put his hand back into the fold of his garment, and when he drew it out, there it was again like his own flesh. 8If they do not believe you or pay attention to the message of the first sign, they should believe the message of the second sign. 9And if they do not believe even these two signs and do not listen to you, take some water from the Nile and pour it on the dry land. The water you take from the Nile will become blood on the dry land”.
