Mark 13:27

24 `But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,

25 and the stars of the heaven shall be falling, and the powers that are in the heavens shall be shaken.

26 `And then they shall see the Son of Man coming in clouds with much power and glory,

27 and then he shall send his messengers, and gather together his chosen from the four winds, from the end of the earth unto the end of heaven.

28 `And from the fig-tree learn ye the simile: when the branch may already become tender, and may put forth the leaves, ye know that nigh is the summer;

29 so ye, also, when these ye may see coming to pass, ye know that it is nigh, at the doors.

30 Verily I say to you, that this generation may not pass away till all these things may come to pass;
