3 While he was sitting upon the Mount of Olives, the disciples approached him privately, saying: “Tell us, When will these things be, and what will be the sign of your presence*+ and of the conclusion* of the system of things?”*+

31 “When the Son of man+ arrives in his glory, and all the angels with him,+ then he will sit down on his glorious throne.+

16 because the Lord* himself will descend from heaven+ with a commanding call, with an archangel’s+ voice and with God’s trumpet,+ and those who are dead in union with Christ will rise first.+
