Luke 21:7 Meaning and Commentary

Luke 21:7

And they asked him
That is, his disciples, when they were come to the Mount of Olives, and as he sat upon that, ( Matthew 24:3 ) saying, master, but when shall these things be?
when the temple shall be destroyed; and one stone shall not be left upon another; and what sign [will there be] when these things shall come to
pass?
which shows that this refers to the destruction of the temple, and so the signs following; (See Gill on Matthew 24:3).

Luke 21:7 In-Context

5 Some [of the disciples] were talking about the temple complex. They noted that it was built with fine stones and decorated with beautiful gifts. So Jesus said,

6 "About these buildings that you see--the time will come when not one of these stones will be left on top of another. Each one will be torn down."

7 The disciples asked him, "Teacher, when will this happen? What will be the sign when all this will occur?"

8 Jesus said, "Be careful that you are not deceived. Many will come using my name. They will say, 'I am he!' and 'The time is near.' Don't follow them!

9 "When you hear of wars and revolutions, don't be terrified! These things must happen first, but the end will not come immediately."
