2 Peter 1:18

And this voice, which came from heaven, we heard,.... Peter, who wrote this epistle, and James and John, the favourite disciples of Christ; and who were a sufficient number to bear witness of what they then saw and heard:when we were with him; and saw his glory, and the glory of Moses and Elias, and were so delighted with his company, and theirs, and with communion with him, that Peter, in the name of the rest, desired to stay there:in the holy mount; the Ethiopic version reads, "in the mountain of his sanctuary"; and so Grotius understands it of Mount Moriah, on which the temple was built, called the holy hill, and the holy hill of Zion; and supposes that this voice was heard in the temple, and that it refers to Joh 12:28, but without any foundation; for the mount on which Christ was transfigured is here meant; and which was either, as is generally said, Tabor, a mountain in Galilee; or it may be Lebanon, which was near Caesarea Philippi, in the parts of which Christ then was: and it is called "holy", from his presence or transfiguration on it, who is the Holy One; just as the land on which Moses was, and the city and temple of Jerusalem, and Mount Sion, and Sinai, are called "holy", from the presence of the holy God there, Ex 3:5.
