Matthew 24:30-40

30 and then shall appear the sign of the Son of Man in the heaven; and then shall all the tribes of the earth smite the breast, and they shall see the Son of Man coming upon the clouds of the heaven, with power and much glory;
31 and he shall send his messengers with a great sound of a trumpet, and they shall gather together his chosen from the four winds, from the ends of the heavens unto the ends thereof.
32 `And from the fig-tree learn ye the simile: When already its branch may have become tender, and the leaves it may put forth, ye know that summer [is] nigh,
33 so also ye, when ye may see all these, ye know that it is nigh -- at the doors.
34 Verily I say to you, this generation may not pass away till all these may come to pass.
35 The heaven and the earth shall pass away, but my words shall not pass away.
36 `And concerning that day and the hour no one hath known -- not even the messengers of the heavens -- except my Father only;
37 and as the days of Noah -- so shall be also the presence of the Son of Man;
38 for as they were, in the days before the flood, eating, and drinking, marrying, and giving in marriage, till the day Noah entered into the ark,
39 and they did not know till the flood came and took all away; so shall be also the presence of the Son of Man.
40 Then two men shall be in the field, the one is received, and the one is left;
