And in the morning, rising up a great while before day - Luke says Luke 4:42, "when it was day." The passage in Mark means, in the original, not literally "a great while before day," but very early, or while there was yet "much appearance of night." The place in Luke means "at daybreak," at the beginning of day. Then, also, there is much appearance of night; and Luke and Mark therefore refer to the same time before it was fully light, or just at daybreak.
And departed into a solitary place, and there prayed - Observe here:
1. that the Saviour, though perfectly holy, regarded the duty of secret prayer as of great importance.
2. that he, sought a solitary place for it - far away from the world and even from his disciples.
3. that it was early in the morning - always the best time, and a time when it should not be omitted.
4. if Jesus prayed, how much more important is it for us!
If Jesus did it in the morning, how much more important is it for us, before the world gets possession of our thoughts; before Satan fills us with unholy feelings; when we rise fresh from beds of repose, and while the world around us is still! David also thus prayed, Psalm 5:3; Psalm 119:147. He that wishes to enjoy religion will seek a place of secret prayer in the morning. If that is omitted, all will go wrong, our piety will wither. The world will fill our thoughts. Temptations will be strong. Through the day, we shall find it impossible to raise our feelings to a state of proper devotion. It will be found to be true universally, "that the religious enjoyment through the day will be according to the state of the heart in the morning, and can therefore be measured by our faithfulness in early secret prayer." How different, too, was the conduct of the Saviour from those who spend the precious hours of the morning in sleep! He knew the value of the morning hours; he rose while the world was still; he saw the light as it spread abroad in the east with fresh tokens of his Father's presence, and joined with the universal creation in offering praise to the everywhere present God.

In the morning a great while before day - By πρωΐ, the morning, is to be understood the whole space of three hours, which finished the fourth watch of the night.
And there prayed - Not that he needed any thing, for in him dwelt all the fullness of the Godhead bodily; but that he might be a pattern to us. Every thing that our blessed Lord did he performed either as our pattern, or as our sacrifice.

And in the morning, rising up a great white before day,.... On the morrow after the sabbath, on the first day in the morning, notwithstanding the fatigue of the former day, through preaching and working miracles; yet he rose up very early while it was very much within the night, as the light and day were coming on, and before the day broke; though it might be broad day before he departed out of the house, as Luke suggests, Luke 4:42,
he went out; out of the house of Simon and Andrew, and out of the city of Capernaum, leaving his disciples and friends behind him:
and departed into a solitary place, and there he prayed; as man, to his God and Father; it may be for his disciples he had lately chosen; for himself, as man, that he might be strengthened as such for service; and for success in his ministry, and that his Gospel might run and be glorified; he chose a desert, and solitary place, for the sake of retirement, from the crowd of people that attended at Peter's door; where he could not be alone, and in private, and as most suitable for the exercise of prayer. His early and private devotion may be an example to us.

And in the morning--that is, of the day after this remarkable sabbath; or, on the first day of the week. His choosing this day to inaugurate a new and glorious stage of His public work, should be noted by the reader.
rising up a great while before day--"while it was yet night," or long before daybreak.
he went out--all unperceived from Peter's house, where He slept.
and departed into a solitary place, and there prayed--or, "continued in prayer." He was about to begin His first preaching and healing circuit; and as on similar solemn occasions (Luke 5:16; Luke 6:12; Luke 9:18, Luke 9:28-29; Mark 6:46), He spent some time in special prayer, doubtless with a view to it. What would one not give to have been, during the stillness of those grey morning hours, within hearing--not of His "strong crying and tears," for He had scarce arrived at the stage for that--but of His calm, exalted anticipations of the work which lay immediately before Him, and the outpourings of His soul about it into the bosom of Him that sent Him! He had doubtless enjoyed some uninterrupted hours of such communings with His heavenly Father ere His friends from Capernaum arrived in search of Him. As for them, they doubtless expected, after such a day of miracles, that the next day would witness similar manifestations. When morning came, Peter, loath to break in upon the repose of his glorious Guest, would await His appearance beyond the usual hour; but at length, wondering at the stillness, and gently coming to see where the Lord lay, he finds it--like the sepulchre afterwards--empty! Speedily a party is made up to go in search of Him, Peter naturally leading the way.

And in the morning. See note on Matthew 8:17.

Rising a great while before day - So did he labour for us, both day and night. Luke 4:42.
