Matthew 24:36 (KJV)

And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.

Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh:

So likewise ye, when ye shall see all these things, know that it is near, even at the doors.

Verily I say unto you, This generation shall not pass, till all these things be fulfilled.

Heaven and earth shall pass away, but my words shall not pass away.

But as the days of Noe were, so shall also the coming of the Son of man be.

For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,

And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.

Then shall two be in the field; the one shall be taken, and the other left.

Two women shall be grinding at the mill; the one shall be taken, and the other left.
