16. And he shall be thy spokesman. God destroys the pretext for his exemption, by assigning to his brother the office of spokesman, and yet does He not put the other in his place; nay, so merciful is the arrangement, that while He yields to His servant’s prayer, He yet confers honor upon him in spite of himself. The offices are thus divided — Moses is to have the authority, Aaron is to be the interpreter. Thus Moses is set before his brother, from no respect to his own dignity; because the grace of God was to shine forth conspicuously in the head no less than in the members; as it is expressed in these words, that “Aaron should be instead of a mouth, and Moses instead of God;” i e. , that he was to dictate what Aaron should faithfully report, and to prescribe what he should obediently follow. By this example did God bear witness that the gifts of the Spirit, as well as our vocations, are distributed by Him at His own good pleasure; and that none excels either in honor or in gifts, except according to the measure of His free bounty. But that the first-born is made subject to the younger, and is only appointed to be his spokesman, whereas God might have accomplished by his hand and labor, what he rather chose to perform by Moses; hence let us learn reverently to regard His judgments, because they are incomprehensible to us, and like a deep abyss. “To be instead of God” is the same as to lead or to direct, or to have the chief command; as the Chaldee Paraphrast (55) renders it, to be the chief or master. It is a very weak calumny of the Arians to abuse this and similar passages, in order to refute the proofs of Christ’s divinity, because there is a great difference in speaking of one as God simply and absolutely, and with circumstantial additions. For we know that the name of God is attributed to every potentate, improperly indeed, yet not unreasonably; as when the devil himself is called “the god of this world,” (2 Corinthians 4:4;) but wherever mention is made of the true Deity, Scripture never profanes that sacred name.
