Whenever the three days and three nights of Matthew 12:40 is brought up in a “discussion” with 6th day crucifixion folks, they frequently argue that it is a Jewish idiom for counting any part of a day as a whole day. I wonder if anyone has documentation that shows that the phrase “x” days and “x”nights was ever used in the first century or before when it didn’t include at least parts of the “x” days and at least parts of the “x” nights?
Would Scripture help to answer your question? Would that count as documentation of the first century and way before that period?
According to Genesis 7:12, the rain of the Noahic Flood was upon the Earth “forty days and forty nights.” Verse 17 of that same chapter says it was on the Earth for just “forty days.” Who would argue that it had to rain precisely 960 hours (40 days x 24 hours) for both of these statements to be true?
In Genesis 42:17 Joseph incarcerated his brothers for three days. Then, according to verse 18, he spoke to them on the third day and released them (all but one, that is).
In 1 Samuel 30:12,13, the phrases “three days and three nights” and “three days” are used interchangeably.
When Queen Esther was about to risk her life by going before the king uninvited, she instructed her fellow Jews to follow her example by not eating “for three days, night or day” (Esther 4:16). The text goes on to tell us that Esther went in unto the king “on the third day” (5:1, emp. added).
Perhaps the most compelling Old Testament passage which clearly testifies that the ancients (at least occasionally) considered a portion of a twenty-four hour period “as the whole of it” is found in 2 Chronicles 10. When Israel asked King Rehoboam to lighten their burdens, he wanted time to contemplate their request, so he instructed Jeroboam and the people of Israel to return “after three days” (2 Chronicles 10:5, emp. added). Verse 12, however, indicates that Jeroboam and the people of Israel came to Rehoboam “on the third day, as the king had directed, saying, ‘ Come back to me the third day’ ” (emp. added). Fascinating, is it not, that even though Rehoboam instructed his people to return “after three days,” they understood this to mean “on the third day.”
From Acts 10, we can glean further insight into the ancient practice of counting consecutive days (in part or in whole) as complete days. Luke recorded how an angel appeared to Cornelius at “about the ninth hour of the day” (approximately 3:00 p.m.; Acts 10:3). “The next day” (10:9) Peter received a vision from God and welcomed visitors sent by Cornelius. “On the next day” (10:23) Peter and the servants of Cornelius departed for Caesarea. “And the following day they entered Caesarea” where Peter taught Cornelius and his household the Gospel (10:24). At one point during Peter’s visit,Cornelius spoke about his encounter with the angel of God. Notice carefully how he began the rehearsal of the event. He stated: “Four days ago to this hour, I was praying in my house during the ninth hour…” (10:30, NASB, emp. added). Although the event actually had occurred only 72 hours (or three literal days) earlier, Cornelius spoke of it as taking place “four days ago to this hour.” Why four days instead of three?
Because according to the first-century method of reckoning time, a part of the first day and a part of the fourth day could be counted as whole days. Surely one can see how this information aligns itself perfectly with Jesus’ burial taking place on Friday and His resurrection occurring on Sunday. A part of Friday, all day Saturday, and a part of Sunday would be considered three days in ancient times, not one or two.
