Charles Ellicott 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 to cover his face.—It was this (recorded by St. Mark and St. Luke, but not by St. Matthew) which gave point to the taunt “Prophesy.” They blindfolded the Prophet and then called on Him to use His power of supernatural vision.

The servants did strike him.—Better, as before, the officers. The two forms of outrage, with the clenched fist and with the open palm, are specified by both St. Matthew and St. Mark.
