impart to him the necessary qualification both as to matter and mode. - Moses' difficulties were now all exhausted, and removed by the assurances of God. But this only brought to light the secret reason in his heart. He did not wish to undertake the divine mission.
Verse 13
“Send, I pray Thee,” he says, “by whom Thou wilt send;” i.e., carry out Thy mission by whomsoever Thou wilt. בּיד שׁלח: to carry out a mission through any one, originally with accus. rei (1Sa 16:20; 2Sa 11:14), then without the object, as here, “to send a person” (cf. 2Sa 12:25; 1Ki 2:25). Before תּשׁלח the word אשׁר is omitted, which stands with בּיד in the construct state (vid., Ges. §123, 3). The anger of God was now excited by this groundless opposition. But as this unwillingness also arose from weakness of the flesh, the mercy of God came to the help of his weakness, and He referred Moses to his brother Aaron, who could speak well, and would address the people for him (Exo 4:14-17). Aaron is called הלּוי, the Levite, from his lineage, possibly with reference to the primary signification of לוה “to connect one's self” (Baumgarten), but not with any allusion to the future calling of the tribe of Levi (Rashi and Calvin). הוּא ידבּר דּבּר speak will he. The inf. abs. gives emphasis to the verb, and the position of הוּא to the subject. He both can and will speak, if thou dost not know it.
verses 14-17
And Aaron is quite ready to do so. He is already coming to meet thee, and is glad to see thee. The statement in Exo 4:27, where Jehovah directs Aaron to go and meet Moses, is not at variance with this. They can both be reconciled in the following simple manner: “As soon as Aaron heard that his brother had left Midian, he went to meet him of his own accord, and then God showed him by what road he must go to find him, viz., towards the desert” (R. Mose ben Nachman). - “Put the words” (sc., which I have told thee) “into his mouth;” and I will support both thee and him in speaking. “He will be mouth to thee, and thou shalt be God to him.” Cf. Exo 7:1, “Thy brother Aaron shall be thy prophet.” Aaron would stand in the same relation to Moses, as a prophet to God: the prophet only spoke what God inspired him with, and Moses should be the inspiring God to him. The Targum softens down the word “God” into “master, teacher.” Moses was called God, as being the possessor and medium of the divine word. As Luther explains it, “Whoever possesses and believes the word of God, possesses the Spirit and power of God,
