A.T. Robertson Commentary Mark 6:47

"And when even was come, the boat was in the midst of the sea, and he alone on the land." — Mark 6:47 (ASV)

When even was come (οψιας γενομενης). The second or late evening, six P.M. at this season, or sunset on.

He alone on the land (κα αυτος μονος ηπ της γης). Another Markan touch. Jesus had come down out of the mountain where he had prayed to the Father. He is by the sea again in the late twilight. Apparently Jesus remained quite a while, some hours, on the beach. "It was now dark and Jesus had not yet come to them" (John 6:17).
