Theophylact of Ohrid, on Heb 12:26

“Whose voice then moved the earth; but now he promiseth, saying: Yet once more, and I will move not only the earth, but heaven also.”

“Do you not see that the One who spoke then was the very Same One who now prophesies to us from heaven? For His voice then, at the time of the giving of the Law, shook the earth. "And Who has now given such a promise: 'Yet once more I will shake not only the earth, but also the heaven.'" We learn of two earthquakes from Scripture: the first was at the giving of the law on Sinai, as David says: "the earth feared" (Ps. 76:9); the second was at the manifestation of Christ in the flesh. For it is said: "all Jerusalem" "was troubled" (Matt. 2:3) and: "the idols of Egypt shall be moved" (Isa. 19:1). For they were shaken, that is, they were deprived of such a state as to deceive those who nourished them, and their power was cast down. Therefore, the expression "yet once more" indicates the third shaking, which will happen after the second coming, or the renewal at the end of the world, when all things will be changed, passing from corruption to incorruption. This is spoken of by the prophet Haggai (Hag. 2:7).”
