A.T. Robertson Commentary Mark 14:35

"And he went forward a little, and fell on the ground, and prayed that, if it were possible, the hour might pass away from him." — Mark 14:35 (ASV)

Fell on the ground (επιπτεν επ της γης). Descriptive imperfect. See him falling. Matthew has the aorist επεσεν.

Prayed (προσηυχετο). Imperfect, prayed repeatedly or inchoative, began to pray. Either makes good sense.

The hour (η ωρα). Jesus had long looked forward to this "hour" and had often mentioned it (John 7:30; John 8:20; 12:23,27; John 13:1). See again in Mr 14:41. Now he dreads it, surely a human trait that all can understand.
