Mark 13:3-7

And as he sat on the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately, Tell us, when shall these things be? and what shall be the sign when these things are all about to be accomplished? And Jesus began to say unto them, Take heed that no man lead you astray. Many shall come in my name, saying, I am he; and shall lead many astray. And when ye shall hear of wars and rumors of wars, be not troubled: these things must needs come to pass; but the end is not yet.
