John Gill Commentary Mark 10:36

"And he said unto them, What would ye that I should do for you?" — Mark 10:36 (ASV)

And he said to them
And also to their mother, and to them by her, what

would you that I should do for you ?
Christ insists upon their telling him the particular thing they wanted to have done for them, before he would give them any promise, though he knew very well what it was they were desirous of.
