And behold there talked with him two men,.... Of great note and fame:
which were Moses and Elias; the one the giver of the law from God to the people "of Israel", as well as the redeemer of them from Egyptian bondage, and who led them through the wilderness, to the borders of Canaan's land; and the other a prophet famous for his zeal for God, and his worship, and who was translated, soul and body, to heaven: these appeared and talked with Christ on the mount; and what they talked of is mentioned in the following verse; See Gill on Matthew 17:3.
there talked with him two men . . . Moses and Elias . . . appeared in glory--"Who would have believed these were not angels had not their human names been subjoined?" [BENGEL]. (Compare Acts 1:10; Mark 16:5). Moses represented "the law," Elijah "the prophets," and both together the whole testimony of the Old Testament Scriptures, and the Old Testament saints, to Christ; now not borne in a book, but by living men, not to a coming, but a come Messiah, visibly, for they "appeared," and audibly, for they "spake."
