Matthew 24:34

31 And he will send out his angels with a great sound of a horn, and they will get his saints together from the four winds, from one end of heaven to the other.

32 Now take an example from the fig-tree: when her branch has become soft and puts out its leaves, you are certain that the summer is near;

33 Even so, when you see all these things, you may be certain that he is near, even at the doors.

34 Truly I say to you, This generation will not come to an end till all these things are complete.

35 Heaven and earth will come to an end, but my words will not come to an end.

36 But of that day and hour no one has knowledge, not even the angels in heaven, or the Son, but the Father only.

37 And as were the days of Noah, so will be the coming of the Son of man.
