³⁰ “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth^[a] will mourn^(A) when they see the Son of Man coming on the clouds of heaven,^(B) with power and great glory.^{[b] 31} And he will send his angels^(C) with a loud trumpet call,^(D) and they will gather his elect from the four winds, from one end of the heavens to the other.

The Day and Hour Unknown^(A)(B)

³⁶ “But about that day or hour no one knows, not even the angels in heaven, nor the Son,^[a] but only the Father.^{(C) 37} As it was in the days of Noah,^(D) so it will be at the coming of the Son of Man. ³⁸ For in the days before the flood, people were eating and drinking, marrying and giving in marriage,^(E) up to the day Noah entered the ark; ³⁹ and they knew nothing about what would happen until the flood came and took them all away. That is how it will be at the coming of the Son of Man.^{(F) 40} Two men will be in the field; one will be taken and the other left.^{(G) 41} Two women will be grinding with a hand mill; one will be taken and the other left.^(H)

⁴² “Therefore keep watch, because you do not know on what day your Lord will come.^{(I) 43} But understand this: If the owner of the house had known at what time of night the thief was coming,^(J) he would have kept watch and would not have let his house be broken into. ⁴⁴ So you also must be ready,^(K) because the Son of Man will come at an hour when you do not expect him.
