Then Jesus sent them out by boat again on Lake Galilee, while he walked alone on a mountain.
"During the day Ennis looked across a great gulf and sometimes saw Jack, a small dot moving across a high meadow as an insect moves across a tablecloth; Jack, in his dark camp, saw Ennis as night fire, a red spark on the huge black mass of mountain. "
In the "fourth watch" - the last quarter of the night - Jesus saw from the mountain that their boat was struggling against the wind. He walked down to them, and didn't stop at the water's edge.
