41 And Moses, answering, said, It is certain that they will not have faith in me or give ear to my voice; for they will say, You have not seen the Lord. 2 And the Lord said to him, What is that in your hand? And he said, A rod. 3 And he said, Put it down on the earth. And he put it down on the earth and it became a snake; and Moses went running from it. 4 And the Lord said to Moses, Put out your hand and take it by the tail: (and he put out his hand and took a grip of it and it became a rod in his hand:) 5 So that they may be certain that the Lord, the God of their fathers, the God of Abraham, of Isaac, and of Jacob, has been seen by you. 6 Then the Lord said to him again, Put your hand inside your clothing. And he put his hand inside his robe: and when he took it out it was like the hand of a leper, as white as snow. 7 And he said, Put your hand inside your robe again. (And he put his hand into his robe again, and when he took it out he saw that it had become like his other flesh.) 8 And if they do not have faith in you or give ear to the voice of the first sign, they will have faith in the second sign. 9 And if they have no faith even in these two signs and will not give ear to your voice, then you are to take the water of the Nile and put it on the dry land: and the water you take out of the river will become blood on the dry land.
10 And Moses said to the Lord, O Lord, I am not a man of words; I have never been so, and am not now, even after what you have said to your servant: for talking is hard for me, and I am slow of tongue.

Commentary on Exodus 4:1-9
(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.
