Luke 17:22-25

And he said unto the disciples, The days will come, when ye shall desire to see one of the days of the Son of man, and ye shall not see it. And they shall say to you, Lo, there! Lo, here! go not away, nor follow after them: for as the lightning, when it lighteneth out of the one part under the heaven, shineth unto the other part under heaven; so shall the Son of man be in his day. But first must he suffer many things and be rejected of this generation.
