SEV Biblia, Chapter 6:51
Y subi a ellos en el barco, y el viento repos; y ellos en gran manera estaban fuera de sí, y se maravillaban;
John Gill's Bible Commentary
Ver. 51. And he went up unto them in the ship , etc..] That is, after Peter had desired he might be bid to come to him upon the water, and having got leave, made an essay; but the wind being boisterous, and beginning to sink, he cried out for help; when Christ stretched out his hand, and saved him; and then he, together with Peter, went up into the ship to the rest of the disciples, as is related by Matthew, ( Matthew 14:28-32), though omitted by this evangelist: and the wind ceased ; from blowing; it was laid at once, as soon as ever Christ entered the ship: and they were sore amazed in themselves beyond measure, and wondered . The Ethiopic version adds, at him; they were astonished, when they found it was Christ, and not a spirit; and they were more amazed at his walking upon the sea; and they marvelled still more abundantly, when they observed that the wind ceased upon his coming into the ship; their amazement was beyond expression, and therefore many words are made use of to signify it by.
Matthew Henry Commentary
Verses 45-56 - The church is often like a ship at sea, tossed with tempests, and no comforted: we may have Christ for us, yet wind and tide against us; but it is a comfort to Christ's disciples in a storm, that their Master is in the heavenly mount, interceding for them. And no difficulties can hinder Christ's appearance for his people, when the set time is come He silenced their fears, by making himself known to them. Our fears ar soon satisfied, if our mistakes are set right, especially our mistake as to Christ. Let the disciples have their Master with them, and all is well. It is for want of rightly understanding Christ's former works that we view his present works as if there never were the like before If Christ's ministers now could cure people's bodily diseases, what multitudes would flock after them! It is sad to think how much mor most care about their bodies than about their souls __________________________________________________________________

Vincent's NT Word Studies
51. Ceased. See on Mark iv. 38.Sore amazed (lian ek perissou existanto). Lit., exceedingly beyond measure. A strong expression peculiar to Mark. jExistanto, were amazed. Compare the cognate noun ekstasiv, and see on Mark v. 42.
Robertson's NT Word Studies
6:51 {They were sore amazed in themselves} (lian en heautois existanto). Only in Mark. Imperfect tense picturing vividly the excited disciples. Mark does not give the incident of Peter's walking on the water and beginning to sink. Perhaps Peter was not fond of telling that story.
