SEV Biblia, Chapter 4:15
Tú hablarás a él, y pondrás en su boca las palabras, y yo seré en tu boca y en la suya, y os enseńaré lo que hayáis de hacer.
Clarke's Bible Commentary - Exodus 4:15
Verse 15. I will be with thy mouth, and with his mouth] Ye shall be both, in all things which I appoint you to do in this business, under the continual inspiration of the Most High.
Matthew Henry Commentary
Verses 10-17 - Moses continued backward to the work God designed him for; there wa much of cowardice, slothfulness, and unbelief in him. We must not judg of men by the readiness of their discourse. A great deal of wisdom an 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 of nature, that his grace in them may appear the more glorious. Christ' 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 dangerou service, let us ask our own hearts if we are not neglecting duties mor easy, and less perilous. The tongue of Aaron, with the head and hear 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 coul speak well, yet could not speak to purpose, unless God gave constan teaching and help; for without the constant aid of Divine grace, the best gifts will fail.
