26. These are that Aaron and Moses. It is not without a cause that Moses so often reasserts that their office was assigned to himself and his brother by the command of God, both that the Israelites may perceive that they were rescued from their deep abyss by divine grace, and that their minds may be recalled to God’s ancient covenant, and may acknowledge that their Fathers’ hope was not in vain; and, finally, that they may hereafter altogether devote themselves to God. There seems, also, to be an indirect antithesis between the armies of the people and two vile and abject men. For they would have been far from being able to bear so weighty a burden, unless God had exceeded all their hopes in working miraculously by their hands. Therefore the Spirit magnifies elsewhere this grace, that God
“led his people, like a flock, by the hand of Moses and Aaron.” (Psalms 77:20)
For what could be less probable than that a great multitude, which would make up many nations, should obey the commands of two men, should be ruled by their counsel, and gathered into one place by their exertions, in order that they should migrate into another land against the will of a very powerful king? For what was their united authority to command twelve armies, separated in their several battalions? What no earthly kings, with all their power and wisdom, their terror and their threats, could effect, God performed by means of two unwarlike men, neither experienced nor renowned; when Moses himself, alarmed by the magnitude of the work, often deprecated the commission entrusted to him. For, at the end of this chapter, he again repeats his excuse, that he was not eloquent, but of hesitating and embarrassed speech. This, then, is the point to which all tends, viz., to assign to God the praise of His loving-kindness, and to heighten His glory. There is some ambiguity in verse 28, for it might be read separately with this sense, that “God not only spoke in the wilderness of Midian, to set Moses over the people in their deliverance, but also in Egypt after some time had elapsed;” thus “on the day,” would mean, “after some time,” but it seems better to me to read the three verses in connection with each other.
