Just for the sake of accumulating data and parallels, here is Genesis 22.3-4:
3 So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him and Isaac his son; and he split wood for the burnt offering, and arose and went to the place of which God had told him. 4 On the third day Abraham raised his eyes and saw the place from a distance.
The Midrash Rabbah here (in
section 1 of chapter 50) offers a list of other significant third days, including:
- The third day of revelation: "And it came to pass on the third day, when it was morning" (Exodus 19.16).
- The third day of resurrection: "After two days he will revive us; on the third day he will raise us up" (Hosea 6.2).
- The third day of Esther: "Now it came to pass on the third day that Esther put on her royal apparel" (Esther 5.1).
- The third day of the tribal ancestors: "And Joseph said unto them the third day: 'This do, and live'" (Genesis 42.18).
So far so good. But we also find this one:
- The third day of Jonah: "And Jonah was in the belly of the fish three days and three nights" (Jonah 2.1).
I suppose this could qualify as rabbinic apologetics, finding parallels even if they are strained. In this sense perhaps the rabbis and Matthew (in 12.40 and 27.62-66) are playing the same game.
Luke does not play this game; he lacks any mention of Jesus rising after three days. For Luke, it is always on the third day.
But I wonder.... In
folio 16a of Tractate Nazir, in the Babylonian Talmud, we find the following:
Now seeing that R. Jose is of the opinion that part of a day counts as a whole day, how is it ever possible for there to be a certified female sufferer from gonorrhoea to offer the [prescribed] sacrifice, for if the issue is observed in the second half of the day, then the first half of the day counts as the period of 'waiting'? — It is possible either if she should have continual issue for three days, or alternatively, if she observes the issue on each of the three days shortly after sunset, so that there is no part of the day that can be reckoned [as a period of cleanness].
A similar debate seems to have occurred with regard to the 30-day Nazarite vow: should the Nazarite poll (and thus end the vow) on the thirtieth day (after only 29 days and a part) or on the thirty-first day (after 30 complete days)? This matter may be found
earlier in the same Tractate as the above:
We have learnt: If a man says, 'I declare myself a nazirite,' he polls on the thirty-first day.3 Now, this fits in well enough with the view of R. Mattena, but how is it to be reconciled with Bar Pada's view? — Bar Pada will say: Consider the clause which follows, [viz.:] Should he poll on the thirtieth day, his obligation is fulfilled. We see, then, that the second clause [of this Mishnah] lends support to his view, whilst the original clause [must be read] as though it contained the word [I declare myself a nazirite for thirty] 'whole' [days]. Does not this second clause need to be reconciled with R. Mattena's view? — He considers part of a day equivalent to a whole day.
But have we not learnt: '[Should someone say,] "I intend to be a nazirite for thirty days," and poll on the thirtieth day, his obligation is not fulfilled'?7 — [We presume that] he said, 'whole days'.
If some rabbis were of the opinion that a part of a day counts as a whole, then perhaps expressions like "on the third day" and "after three days" (= part of the first day, all of the second day, and part of the third day) might have been equated even without a specific apologetic purpose in trying to harmonize two passages. Perhaps Matthew was of this mindset, but Luke either was not or simply did not understand it.
Again, I am just adding sticks to the pile. I am not sure about this yet.
