In context
6Furthermore, the LORD said to Moses, “Put your hand inside your cloak. ” So he put his hand inside his cloak, and when he took it out, his hand was leprous, white as snow. 7“Put your hand back inside your cloak,” said the LORD. 8And the LORD said, “If they refuse to believe you or heed the witness of the first sign, they may believe that of the second. 9But if they do not believe even these two signs or listen to your voice, take some water from the Nile and pour it on the dry ground. Then the water you take from the Nile will become blood on the ground.”
