10 But Moses pleaded with the Lord, "OÂ Lord, I'm not very good with words. I never have been, and I'm not now, even though you have spoken to me. I get tongue-tied, and my words get tangled." 11 Then the Lord asked Moses, "Who makes a person's mouth? Who decides whether people speak or do not speak, hear or do not hear, see or do not see? Is it not I, the Lord ? 12 Now go! I will be with you as you speak, and I will instruct you in what to say." 13 But Moses again pleaded, "Lord, please! Send anyone else." 14 Then the Lord became angry with Moses. "All right," he said. "What about your brother, Aaron the Levite? I know he speaks well. And look! He is on his way to meet you now. He will be delighted to see you. 15 Talk to him, and put the words in his mouth. I will be with both of you as you speak, and I will instruct you both in what to do. 16 Aaron will be your spokesman to the people. He will be your mouthpiece, and you will stand in the place of God for him, telling him what to say. 17 And take your shepherd's staff with you, and use it to perform the miraculous signs I have shown you."

(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.
