John Gill Commentary Mark 10:51

"And Jesus answered him, and said, What wilt thou that I should do unto thee? And the blind man said unto him, Rabboni, that I may receive my sight." — Mark 10:51 (ASV)

And Jesus answered and said to him
Being come to him, and standing before him:

what do you want that I should do to you ?
What means this vehement cry? what is it you design by mercy? is it money you ask for, to relieve your wants? or is it that your sight may be restored?

The blind man said to him, Lord ;
"Rabboni", or, as the Syriac version reads it; "Rabbi"; you, great master in Israel, and Lord, of the whole world, my request to you, and which you, are, able to effect; is,

that I might receive my sight; (See Gill on Matthew 20:33).
