Matthew 24:3,29,30,32,33
As he sat on the Mount of Olives, the disciples came to him privately, saying, Tell us, when will these things be, and what will be the sign of your coming and of the close of the age?
Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken.
Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.
From the fig tree learn its lesson: as soon as its branch becomes tender and puts out its leaves, you know that summer is near.
So also, when you see all these things, you know that he is near, at the very gates.
