Mark 13:4

Tell us, when shall these things be? and what shall be the sign when all these things shall be fulfilled?

"Tell us, when will these things be? What is the sign that these things are all about to be fulfilled?"

Tell us, when shall these things be? and what `shall be' the sign when these things are all about to be accomplished?

`Tell us when these things shall be? and what `is' the sign when all these may be about to be fulfilled?'

“Tell us, when will these things happen? And what will be the sign that they are about to be fulfilled?”
