SEV Biblia, Chapter 8:31
Y comenz a ensearles, que convenía que el Hijo del hombre padeciese mucho, y ser reprobado de los ancianos, y de los príncipes de los sacerdotes, y de los escribas; y ser muerto, y resucitar despus de tres días.
John Gill's Bible Commentary
Ver. 31. And he began to teach them , etc..] For as yet he had said nothing to them about his sufferings and death, at least in express terms; but now they being firmly established in the faith of him, as the Messiah, he thought it proper to inform them, that the son of man must suffer many things ; meaning himself, as that he should be betrayed, apprehended, and bound, should be smitten, spit upon, buffeted, and scourged; and which things must be done, and he suffer them, because it was so determined by God, and foretold in the Scriptures: and be rejected of the elders, and of the chief priests and Scribes ; which composed the grand sanhedrim of the nation, and are the builders that were prophesied of by whom he should be rejected, ( <19B822> Psalm 118:22), and be killed ; in a violent manner; his life be taken away by force, without law, or justice: and after three days rise again : not after three days were ended, and on the fourth day, but after the third day was come; that is, on the third day, as the Syriac, Arabic, Persic, and Ethiopic versions read; and even the Pharisees themselves thus understood Christ, ( Matthew 27:63,64), so the phrase, after eight days, is used for the eighth day, being come, or that same day a week later; (see Luke 9:28) compared with ( Matthew 17:1 John 20:26).
Matthew Henry Commentary
Verses 27-33 - These things are written, that we may believe that Jesus is the Christ the Son of God. These miracles of our Lord assure us that he was no conquered, but a Conqueror. Now the disciples are convinced that Jesu is the Christ; they may bear to hear of his sufferings, of which Chris here begins to give them notice. He sees that amiss in what we say an do, of which we ourselves are not aware, and knows what manner of spirit we are of, when we ourselves do not. The wisdom of man is folly when it pretends to limit the Divine counsels. Peter did not rightl understand the nature of Christ's kingdom.

Robertson's NT Word Studies
8:31 {He began to teach them} (erxato didaskein autous). Mark is fond of this idiom, but it is not a mere rhetorical device. #Mt 16:21 expressly says "from that time." They had to be told soon about the approaching death of Jesus. The confession of faith in Jesus indicated that it was a good time to begin. Death at the hands of the Sanhedrin (elders, chief priests, and scribes) in which Pharisees and Sadducees had about equal strength. The resurrection on the third day is mentioned, but it made no impression on their minds. this rainbow on the cloud was not seen. {After three days} (meta treis hemeras). #Mt 16:21 has "the third day" (tei tritei hemerai) in the locative case of point of time (so also #Lu 9:22). There are some people who stickle for a strict interpretation of "after three days" which would be "on the fourth day," not "on the third day." Evidently Mark's phrase here has the same sense as that in Matthew and Luke else they are hopelessly contradictory. In popular language "after three days" can and often does mean "on the third day," but the fourth day is impossible.
