Third possibility: Jesus was a man who never rose from the grave.
Just another of the 400 plus self contradictions in the Bible that not even the experts can agree about.
here let me give you the whole section this time, with my software:
"
MATTHEW 12:40 (cf. John 19:14)If Jesus was crucified on Friday, how could He have been in the grave three days and nights?
PROBLEM: Christ rose on Sunday (Matt. 28:1), but He stated that He would be three days and three nights in the heart of the earth. If Christ was crucified on Friday, how could He have been three days and three nights in the earth and rise on Sunday only two days later?
SOLUTION 1: Some scholars believe Jesus was in the grave for three full days and nights (72 hours), being crucified on Wednesday. They offer the following in support of this contention.
First, they insist that this is the literal meaning of the phrase three days and nights. Second, they point out that, on the view that Jesus was crucified on Friday, there is no explanation for what He did on Wednesday. All other days are accounted for. Third, they argue that the passover was not a fixed day (Friday), but floated.
SOLUTION 2: Most biblical scholars believe that Jesus was crucified on Friday. They take the phrase three days and nights to be a Hebrew figure of speech referring to any part of three days and nights. They offer the following in support of their position.
First, the phrase day and night does not necessarily mean a complete 24 hour period. The psalmists reference to meditating day and night on Gods Word does not mean one has to read the Bible all day and all night (Ps. 1:2).
Second, it is clear from the use of the phrase three days and three nights in the Book of Esther that it does not mean 72 hours. For, although they fasted three days and nights (4:16) between the time they started and the time she appeared before the king, the passage states that Esther appeared before the king on the third day (5:1). If they began on Friday, then the third day would be Sunday. Hence, three days and nights must mean any part of three days and nights.
Third, Jesus used the phrase on the third day to describe the time of His resurrection after His crucifixion (Matt 16:21; 17:23; 20:19; cf. 26:61). But, on the third day cannot mean after three days which 72 hours demands. On the other hand, the phrase on the third day or three days and nights can be understood to mean within three days and nights.
Fourth, this view fits best with the chronological order of events as given by Mark (cf. 14:1), as well as the fact that Jesus died on Passover day (Friday) to fulfill the conditions of being our Passover Lamb (1 Cor. 5:7; cf. Lev. 23:515)."
