Luke 21:7

7 So they asked Him, saying, "Teacher, but when will these things be? And what sign will there be when these things are about to take place?"

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 Then, as some spoke of the temple, how it was adorned with beautiful stones and donations, He said,

6 "These things which you see--the days will come in which not one stone shall be left upon another that shall not be thrown down."

7 So they asked Him, saying, "Teacher, but when will these things be? And what sign will there be when these things are about to take place?"

8 And He said: "Take heed that you not be deceived. For many will come in My name, saying, 'I am He,' and, 'The time has drawn near.' Therefore do not go after them.

9 But when you hear of wars and commotions, do not be terrified; for these things must come to pass first, but the end will not come immediately."
