Christ's life was a more precious life than any man's, and peculiarly his own, in such sense as another man's, is not his own; and his soul also was an only one, it was not polluted with original sin, as the souls of other men are; it was pure and holy: the word here used is sometimes rendered "desolate" and "solitary"; see Ps 25:16; and it may have this sense here, and be translated "my lonely" or "solitary one" ; he being forsaken by God, and deserted by his disciples; his soul was in darkness, sorrow, and distress, wherefore he prays it might be delivered "from the power of the dog"; either Satan is so called for his malice and envy, who had put it into the heart of Judas to betray him, and had filled the Pharisees with envy at him, and who through it delivered him to Pilate; or the impure, cruel, and wicked Roman soldiers, and in short all his crucifiers; called in the plural number "dogs", See Gill on "Ps 22:16".
