Mark 1:35

My voice shalt thou hear in the morning, O LORD; in the morning will I direct my prayer unto thee, and will look up.

For my love they are my adversaries: but I give myself unto prayer.

And when he had sent them away, he departed into a mountain to pray. And when even was come, the ship was in the midst of the sea, and he alone on the land. And he saw them toiling in rowing; for the wind was contrary unto them: and about the fourth watch of the night he cometh unto them, walking upon the sea, and would have passed by them.

And when it was day, he departed and went into a desert place: and the people sought him, and came unto him, and stayed him, that he should not depart from them.

And it came to pass in those days, that he went out into a mountain to pray, and continued all night in prayer to God.

And he came out, and went, as he was wont, to the mount of Olives; and his disciples also followed him. And when he was at the place, he said unto them, Pray that ye enter not into temptation. And he was withdrawn from them about a stone's cast, and kneeled down, and prayed, Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done. And there appeared an angel unto him from heaven, strengthening him. And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground. And when he rose up from prayer, and was come to his disciples, he found them sleeping for sorrow, And said unto them, Why sleep ye? rise and pray, lest ye enter into temptation.

Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.

When Jesus therefore perceived that they would come and take him by force, to make him a king, he departed again into a mountain himself alone.
