Mark 13:1-4

1 Then as He went out of the temple, one of His disciples said to Him, "Teacher, see what manner of stones and what buildings are here!"

2 And Jesus answered and said to him, "Do you see these great buildings? Not one stone shall be left upon another, that shall not be thrown down."

3 Now as He sat on the Mount of Olives opposite the temple, Peter, James, John, and Andrew asked Him privately,

4 "Tell us, when will these things be? And what will be the sign when all these things will be fulfilled?"
