27. And the Lord said to Aaron. When, from the long lapse of time, Aaron must have supposed that his brother had died in exile, he now receives the joyful announcement, from the mouth of God, that he is alive; and not only so, but he is excited with the hope of His special favor; for, although God does not explain in detail what he had decreed to do and prepared, yet, by his revelation, he promises him something unusual and unexpected. But the brevity of the command is remarkable, for God says not a word of the deliverance, but desires him to be the disciple of his younger brother; and although, by his promptitude, he manifested the greatest zeal and anxiety to obey, still he is not put on an equality with Moses, who is slow, and dubious, and vacillating, and almost supine; but he is commanded to learn of him the design of God. Only, lest he should question his own and his brother’s vocation, he is instructed by a divine vision, that God is the author of the whole transaction, which serves as a recommendation of the verbal information he is to receive. For although Aaron was the messenger of God, and the organ of the Holy Spirit, we still see that he was not exempt from the usual condition to which we are subjected, of hearing God’s word at the mouth of man. If, then, there are any who object to be taught by the medium of man’s voice, they are not worthy of having God as their Teacher and Master; for it is soon after added, that Moses related all that was commanded him, as well as the great power which had been delegated to him of working miracles. But Aaron himself, although the elder, not only paid honor to his brother, whom he knew to be a Prophet of the Lord; but willingly submitted himself to him as to an angel. The kiss is mentioned as a sign of recognition, by which he testified the firmness of his faith.
