30And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. 31And 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. 32Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: 33So likewise ye, when ye shall see all these things, know that it is near, even at the doors.34Verily I say unto you, This generation shall not pass, till all these things be fulfilled. 35Heaven and earth shall pass away, but my words shall not pass away. 36But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
