(40) As Jonas was three days and three nights.--To understand the words rightly, we have to remember the prominence which our Lord gives to the history of Jonah, and to the repentance of the men of Nineveh, in this and in the parallel passage of Luke 11:29, and in answer to another demand for a sign in Matthew 16:4. In the other passages "the sign of the prophet Jonas" appears with a vague mysteriousness, unexplained. Not a few critics have accordingly inferred from this difference that the explanation given by St. Matthew was an addition to the words actually spoken by our Lord, and that "the sign of the prophet Jonas" was sufficiently fulfilled by His preaching repentance to the wicked and adulterous generation as Jonah had done to the Ninevites. Against this view, however, it may be urged:--(1) That Jonah's work as a preacher was not a "sign" in any sense, and that nothing in his history had this character, except the two narratives of the whale (Jonah 1:17) and the gourd (Jonah 4:6-10). Any reference to the latter is, of course, out of the question; and it remains therefore, in any case, that we must look to the former as that to which our Lord alluded. (2) That the very difficulty presented by the prediction of "three days and three nights" as compared with the six-and-thirty hours (two nights and one day) of the actual history of the Resurrection, is against the probability of the verse having been inserted as a prophecy after the event. (3) That if we believe that our Lord had a distinct prevision of His resurrection, and foretold it, sometimes plainly and sometimes in dark sayings--and of this the Gospels leave no room for doubt (Matthew 16:21; Matthew 26:32; John 2:19)--then the history of Jonah presented an analogy which it was natural that He should notice. It does not necessarily follow that this use of the history as a prophetic symbol of the Resurrection requires us to accept it in the very letter of its details. It was enough, for the purposes of the illustration, that it was familiar and generally accepted. The purely chronological difficulty is explained by the common mode of speech among the Jews, according to which, any part of a day, though it were but a single hour, was for legal purposes considered as a whole. An instance of this mode of speech is found in 1Samuel 30:12-13, and it is possible that in the history of Jonah itself the measurement of time is to be taken with the same laxity.

Some incidental facts are worth noticing: (1) that the word translated "whale" may stand vaguely for any kind of sea-monster; (2) that "the heart of the earth," standing parallel as it does to "the heart of the seas," the "belly of hell"--i.e., Sheol and Hades--in Jonah 2:2-3, means more than the rock-hewn sepulchre, and implies the descent into Hades, the world of the dead, which was popularly believed to be far below the surface of the earth; (3) that the parable has left its mark on Christian art, partly in the constant use of Jonah as a type of our Lord's resurrection, and partly in that of the jaws of a great whale-like monster as the symbol of Hades; (4) that the special character of the psalm in Jonah 2, corresponding as it does so closely (Jonah 2:6) with Psalm 16:10-11, may well be thought to have prompted our Lord's reference to it.

Verse 40. - Matthew only. For as Jonas (Jonah, Revised Version) was three days and three nights in the whale's belly. Verbally from the LXX. of Jonah 1:17 (2:1). So shall the Son of man be three days and three nights in the heart of the earth. Since, so far as the balance of evidence goes (cf., however, Bishop Westcott, 'Introduction,' p. 344, edit. 1872), the Crucifixion was on Friday and the Resurrection on Sunday, the actual time between them was only one clear day and two parts of days (which might fairly be called three days) and two whole nights. The reckoning, therefore, here is, strictly speaking, inaccurate. The words are perhaps a mere adaptation of the phrase in Jonah, and are here used only to roughly mark the time of our Lord's stay in the grave. Observe, however, that the addition of" nights" tends to emphasize the reality of our Lord's stay there. It was a matter of days and nights; he spent both kinds of earthly time "in the heart of the earth" (cf. Matthew 4:2, note). It will be noticed that the inaccuracy of the wording would, if modern Western habits were alone to be considered, make it most unlikely that the phrase is a later addition; but in view of the early Christian and Jewish method of illustrating events by passages of Scripture which do not apply in all respects, the improbability is not so great as would at first sight appear. However, upon our present information, we must say that the phrase was spoken by our Lord himself, and that although the exact time of his stay in the grave was well known to the early believers, they continued to repeat the saying in the form in which the Lord left it. In the heart of the earth. The form of the expression is derived from Jonah 2:3 (4), "in the heart of the seas" (cf. Exodus 15:8), and would therefore appear to mean some deeper place than the rock-hewn sepulchre. Hence many commentators, beginning with Irenaeus ('Adv. Haer.,' V. 31.) and Tertullian ('De Anima,' Iv.), understand it as directly denoting the place of departed spirits. Ephesians 4:9 ("the lower parts of the earth"), on the contrary, probably refers to the earth as such in contrast to heaven.

12:38-45 Though Christ is always ready to hear and answer holy desires and prayers, yet those who ask amiss, ask and have not. Signs were granted to those who desired them to confirm their faith, as Abraham and Gideon; but denied to those who demanded them to excuse their unbelief. The resurrection of Christ from the dead by his own power, called here the sign of the prophet Jonah, was the great proof of Christ's being the Messiah. As Jonah was three days and three nights in the whale, and then came out again alive, thus Christ would be so long in the grave, and then rise again. The Ninevites would shame the Jews for not repenting; the queen of Sheba, for not believing in Christ. And we have no such cares to hinder us, we come not to Christ upon such uncertainties. This parable represents the case of the Jewish church and nation. It is also applicable to all those who hear the word of God, and are in part reformed, but not truly converted. The unclean spirit leaves for a time, but when he returns, he finds Christ is not there to shut him out; the heart is swept by outward reformation, but garnished by preparation to comply with evil suggestions, and the man becomes a more decided enemy of the truth. Every heart is the residence of unclean spirits, except those which are temples of the Holy Ghost, by faith in Christ.For as Jonas was three days and three nights in the whale's belly,.... Or "in the belly of a great fish", as is said, Jonah 1:17 for that it was a whale, is not there said, nor is it certain it was; nor from the smallness of its swallow, is it thought probable it should; nor does the word here used, necessarily imply one, but some large fish; nor are there whales in the Phoenician Sea: it might be a kind of a sea dog, called Carcharias, and sometimes Lamia, or Lamina, from its vast swallow; in which whole men; even in coats of mail, have been found. However, be it what it will, Jonas was three days and three nights in the belly of it; which agrees with the account in the above mentioned place, and is the sign Christ speaks of in the foregoing verse; and a very great sign and miracle it was, that being swallowed down by such a fish, he should remain in the belly of it three days and three nights, as one dead; for, without a miracle, he could not have lived an hour; and on the third day, as one raised from the dead, be cast out of it upon the dry land; which was a very eminent type of the death, burial, and resurrection of Christ, as appears by what follows. The Jews reckon up several wonders or miracles in this case of Jonah's; as that a fish was prepared to swallow him up, and he not drowned in the sea; and that this was prepared for him from the creation of the world; that he should be three days and three nights in the fish's belly, and be alive; and that he should retain his senses and his understanding, so as to be able to pray: they represent him also as if he was in the state of the dead (l), and that the fish itself was dead, and was quickened again. According to Josephus, after he had been carried 250 miles in the Hellespont of the Euxine Sea, he was cast ashore (m).

So shall the Son of man be three days and three nights in the heart of the earth. That Christ means himself by the "son of man", there is no reason to doubt; and his being laid in a tomb, dug out of a rock, is sufficient to answer this phrase, "the heart of the earth", in distinction from the surface of it; but some difficulty arises about the time of his continuing there, and the prediction here made agreeable to the type: for it was on the sixth day of the week, we commonly call "Friday", towards the close, on the day of the preparation for the sabbath, and when the sabbath drew on, that the body of Christ was laid in the sepulchre; where it lay all the next day, which was the sabbath of the Jews, and what we commonly call "Saturday"; and early on the first of the week, usually called "Sunday", or the Lord's day, he rose from the dead; so that he was but one whole day, and part of two, in the grave. To solve this difficulty, and set the matter in a clear light, let it be observed, that the three days and three nights, mean three natural days, consisting of day and night, or twenty four hours, and are what the Greeks call "night days"; but the Jews have no other way of expressing them, but as here; and with them it is a well known rule, and used on all occasions, as in the computation of their feasts and times of mourning, in the observance of the passover, circumcision, and divers purifications, that , "a part of a day is as the whole" (n): and so, whatever was done before sun setting, or after, if but an hour, or ever so small a time, before or after it, it was reckoned as the whole preceding, or following day; and whether this was in the night part, or day part of the night day, or natural day, it mattered not, it was accounted as the whole night day: by this rule, the case here is easily adjusted; Christ was laid in the grave towards the close of the sixth day, a little before sun setting, and this being a part of the night day preceding, is reckoned as the whole; he continued there the whole night day following, being the seventh day; and rose again early on the first day, which being after sun setting, though it might be even before sun rising, yet being a part of the night day following, is to be esteemed as the whole; and thus the son of man was to be, and was three days and three nights in the grave; and which was very easy to be understood by the Jews; and it is a question whether Jonas was longer in the belly of the fish.
