And they asked him, saying: Master, when shall these things be? and what shall be the sign when they shall begin to come to pass?

And they asked him saying, Teacher, when then shall these things be; and what is the sign when these things are going to take place?

"Rabbi, when will this be?" they asked Him, "and what will be the token given when these things are about to take place?"

And they said to him, Master, when will these things be? and what sign will there be when these events are to take place?

Then they questioned him, saying: "Teacher, when will these things be? And what will be the sign when these things will happen?"

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.
