These verses stood out as the many different times Jesus prayed, and John 17 to me was in front of his disciples, but mostly he separated himself alone. Today read the list of the word “pray” in the Gospels for reading today.
Matthew 14:23 And when he had sent the multitudes away, he went up into a mountain apart to pray: and when the evening was come, he was there alone.
Luke 6:12 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.
Mark 1:35 And in the morning, rising up a great while before day, he went out, and departed into a solitary place, and there prayed.
