41 Then Moses answered, "But suppose they do not believe me or listen to me, but say, "The Lord did not appear to you.' " 2 The Lord said to him, "What is that in your hand?" He said, "A staff." 3 And he said, "Throw it on the ground." So he threw the staff on the ground, and it became a snake; and Moses drew back from it. 4 Then the Lord said to Moses, "Reach out your hand, and seize it by the tail"-so he reached out his hand and grasped it, and it became a staff in his hand- 5 "so that they may believe that the Lord, the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you." 6 Again, the Lord said to him, "Put your hand inside your cloak." He put his hand into his cloak; and when he took it out, his hand was leprous, as white as snow. 7 Then God said, "Put your hand back into your cloak"-so he put his hand back into his cloak, and when he took it out, it was restored like the rest of his body- 8 "If they will not believe you or heed the first sign, they may believe the second sign. 9 If they will not believe even these two signs or heed you, you shall take some water from the Nile and pour it on the dry ground; and the water that you shall take from the Nile will become blood on the dry ground."
10 But Moses said to the Lord, "O my Lord, I have never been eloquent, neither in the past nor even now that you have spoken to your servant; but I am slow of speech and slow of tongue." 11 Then the Lord said to him, "Who gives speech to mortals? Who makes them mute or deaf, seeing or blind? Is it not I, the Lord? 12 Now go, and I will be with your mouth and teach you what you are to speak." 13 But he said, "O my Lord, please send someone else." 14 Then the anger of the Lord was kindled against Moses and he said, "What of your brother Aaron the Levite? I know that he can speak fluently; even now he is coming out to meet you, and when he sees you his heart will be glad. 15 You shall speak to him and put the words in his mouth; and I will be with your mouth and with his mouth, and will teach you what you shall do. 16 He indeed shall speak for you to the people; he shall serve as a mouth for you, and you shall serve as God for him. 17 Take in your hand this staff, with which you shall perform the signs."

(Read Exodus 4:1-9)
Moses objects, that the people would not take his word, unless he showed them some sign. God gives him power to work miracles. But those who are now employed to deliver God's messages to men, need not the power to work miracles: their character and their doctrines are to be tried by that word of God to which they appeal. These miracles especially referred to the miracles of the Lord Jesus Christ. It belonged to Him only, to cast the power of the devil out of the soul, and to heal the soul of the leprosy of sin; and so it was for Him first to cast the devil out of the body, and to heal the leprosy of the body.
Commentary on Exodus 4:10-17
(Read Exodus 4:10-17)
Moses continued backward to the work God designed him for; there was much of cowardice, slothfulness, and unbelief in him. We must not judge of men by the readiness of their discourse. A great deal of wisdom and true worth may be with a slow tongue. God sometimes makes choice of those as his messengers, who have the least of the advantages of art or nature, that his grace in them may appear the more glorious. Christ's disciples were no orators, till the Holy Spirit made them such. God condescends to answer the excuse of Moses. Even self-diffidence, when it hinders us from duty, or clogs us in duty, is very displeasing to the Lord. But while we blame Moses for shrinking from this dangerous service, let us ask our own hearts if we are not neglecting duties more easy, and less perilous. The tongue of Aaron, with the head and heart of Moses, would make one completely fit for this errand. God promises, I will be with thy mouth, and with his mouth. Even Aaron, who could speak well, yet could not speak to purpose, unless God gave constant teaching and help; for without the constant aid of Divine grace, the best gifts will fail.
