8 If they do not believe you or pay attention to the message of the first sign, they should believe the message of the second sign.
9 And 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.
10 Moses, however, said to the Lord, “If you please, my Lord, I have never been eloquent, neither in the past nor now that you have spoken to your servant; but I am slow of speech and tongue.”
11 The Lord said to him: Who gives one person speech? Who makes another mute or deaf, seeing or blind? Is it not I, the Lord?
12 Now go, I will assist you in speaking and teach you what you are to say.
13 But he said, “If you please, my Lord, send someone else!”
14 Then the Lord became angry with Moses and said: I know there is your brother, Aaron the Levite, who is a good speaker; even now he is on his way to meet you. When he sees you, he will truly be glad.
