Mark 6:50 Meaning and Commentary

Mark 6:50

For they all saw him, and were troubled
Had it been only seen by one, it might have been thought a fancy, and the effect of mere imagination; but as every one saw it, it was out of all doubt that so it was, and which gave them the greater concern:

and immediately he talked with them;
as soon as they saw him, "that very moment", as the Syriac renders it; that so by hearing his voice their fears might be allayed:

and saith unto them, be of good cheer, it is I, be not afraid;
(See Gill on Matthew 14:27).

Mark 6:50 In-Context

48 He saw that his disciples were straining at the oars, because they were rowing against the wind; so sometime between three and six o'clock in the morning, he came to them, walking on the water. He was going to pass them by,
49 but they saw him walking on the water. "It's a ghost!" they thought, and screamed.
50 They were all terrified when they saw him. Jesus spoke to them at once, "Courage!" he said. "It is I. Don't be afraid!"
51 Then he got into the boat with them, and the wind died down. The disciples were completely amazed,
52 because they had not understood the real meaning of the feeding of the five thousand; their minds could not grasp it.
