15 And thou shalt speak unto him, and put words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do.
15 You shall speak to him and put words in his mouth; I will help both of you speak and will teach you what to do.
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 both what to do.
15 You'll speak to him and tell him what to say. I'll be right there with you as you speak and with him as he speaks, teaching you step by step.
15 Now you shall speak to him and put the words in his mouth. And I will be with your mouth and with his mouth, and I will teach you what you shall do.
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.
Matthew Henry's Commentary on Exodus 4:15
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.
