John Gill Commentary Mark 14:65

"And some began to spit on him, and to cover his face, and to buffet him, and to say unto him, Prophesy: and the officers received him with blows of their hands." — Mark 14:65 (ASV)

And some began to spit on him
The men that held him, (Luke 22:6), fulfilling the prophecy in (Isaiah 50:6);

and to cover his face ;
with a veil, or linen cloth, to blindfold: him, as a person unworthy to behold the light: or rather, in order to make sport with him:

and to buffet him ;
with their double fists;

and to say unto him, prophesy .
The Arabic version adds, "unto us, O Christ, who it is that has buffeted you now?" that gave you the last blow? and to the same purpose the Ethiopic. The Persic version adds, "and deliver yourself";

and the servants did strike him with the palms of their hands .
The Syriac version renders it, "on his cheeks": they gave him slaps on the face. These were the officers of the high priest, that used him in this indecent manner. This clause is omitted in the Ethiopic version.
