Luke 5:16

And he withdrew himself into the wilderness
Into a desert place, that he might have rest from the fatigues of preaching and healing diseases; and being alone, and free from company, might have an opportunity for private prayer to God, for so it lows:

and prayed;
this is to be understood of Christ, as man: as God, he is the object of prayer, and petitions are often addressed unto him; and as mediator, he offers up the prayers of all saints, and presents them to his Father; which are acceptable to him, through the incense of his mediation; and as man, he prayed himself: what he now prayed for, is not known; sometimes he prayed for his disciples, and for all that should believe; for their conversion, sanctification, union, perseverance, and glorification; and sometimes for himself, that the cup might pass from him, and he be saved from death; but always with submission to the will of his Father.
