And Jonas began to enter into the city one day’s journey: and he cried, and said: Yet forty days, and Ninive shall be destroyed.

“Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him... Jonah proclaimed destruction to the Ninevites; but they, repenting of their sins, propitiated God by prayer, and obtained salvation, although they were aliens [to the covenant] of God.”

“For He never makes a public display of our sins, except at any time He sees men insensible to them. For when He says "ye saw me hungry, and fed me not: and thirsty and gave me no drink," He speaks thus at the present time in order that we may not hear these words in time to come. He threatens, He exposes us in this world, that He may not have to expose us in the other: even as He threatened to overthrow the city of the Ninevites for the very reason that He might not overthrow it. For if He wished to publish our sins He would not announce beforehand that He would publish them: but as it is He does make this announcement in order that being sobered by the fear of exposure, if not also by the fear of punishment we may purge ourselves from them all.”

“And Jonah began to enter into the city a day's journey,.... As soon as he came to it, he did not go into an inn, to refresh himself after his wearisome journey; or spend his time in gazing upon the city, and to observe its structure, and the curiosities of it; but immediately sets about his work, and proclaims what he was bid to do; and before he could finish one day's journey, he had no need to proceed any further, the whole city was alarmed with his preaching, was terrified with it, and brought to repentance by it: and he cried; as he went along; he lifted up his voice like a trumpet, that everyone might hear; he did not mutter it out, as if afraid to deliver his message, but cried aloud in the hearing of all; and very probably now and then made a stop in the streets, where there was a concourse of people, or where more streets met, and there, as a herald, proclaimed what he had to say: and said, yet forty days, and Nineveh shall be overthrown; not by a foreign army besieging and taking it, which was not probable to be done in such a space of time, but by the immediate power of God; either by fire from heaven, as he overthrow Sodom and Gomorrah, their works being like theirs, as Kimchi and Ben Melech observe, or by an earthquake; that is, within forty days, or at the end of forty days, as the Targum; not exceeding such a space, which was granted for their repentance, which is implied, though not expressed; and must be understood with this proviso, except it repented, for otherwise why is any time fixed? and why have they warning given them, or the prophet sent to them? and why were they not destroyed at once, as Sodom and Gomorrah, without any notice? doubtless, so it would have been, had not this been the case. The Septuagint version very wrongly reads, "yet three days", &c. and as wrongly does Josephus (q) make Jonah to say, that in a short time they would lose the empire of Asia, when only the destruction of Nineveh is threatened; though, indeed, that loss followed upon it. (q) Antiqu. l. 9. c. 10. sect. 2.”

“Yet forty days - Both the Septuagint and Arabic read three days. Probably some early copyist of the Septuagint, from whom our modern editions are derived, mistook the Greek numerals μ forty for γ three; or put the three days' journey in preaching instead of the forty days mentioned in the denunciation. One of Kennicott's MSS., instead of ארבעים arbaim, forty, has שלשים sheloshim, thirty: but the Hebrew text is undoubtedly the true reading; and it is followed by all the ancient versions, the Septuagint and Vulgate excepted. thus God gives them time to think, reflect, take counsel, and return to him. Had they only three days' space, the denunciation would have so completely confounded them, as to excite nothing but terror, and prevent repentance and conversion.”

“Journey. He records what he said the first day, though he seems to have preached many (Theodoret) even during forty days, after which time (Haydock) he expected the city would fall, and therefore retired out of the walls, chap. iv. — Forty. Septuagint three. St. Justin Martyr, (Dialogue with Trypho) “three, or forty-three.” Theodoret thinks that the mistake was made by some ancient transcriber, and has since prevailed in all the copies of the Septuagint. All the rest have forty. St. Augustine (City of God xviii. 44.) believes the Septuagint placed three for a mysterious reason. Origen (hom. xvi. Num.) suggests that the prophet determined the number, and hence God did not execute the threat. (Calmet) — This and many other menaces are conditional. If men repent, God will change his sentence. (St. Chrysostom; St. Gregory, Mor. xvi. 18.) (Worthington)”

“a day's journey--not going straight forward without stopping: for the city was but eighteen miles in length; but stopping in his progress from time to time to announce his message to the crowds gathering about him. Yet forty days, and Nineveh shall be overthrown--The commission, given indefinitely at his setting out, assumes now on his arrival a definite form, and that severer than before. It is no longer a cry against the sins of Nineveh, but an announcement of its ruin in forty days. This number is in Scripture associated often with humiliation. It was forty days that Moses, Elijah, and Christ fasted. Forty years elapsed from the beginning of Christ's ministry (the antitype of Jonah's) to the destruction of Jerusalem. The more definite form of the denunciation implies that Nineveh has now almost filled up the measure of her guilt. The change in the form which the Ninevites would hear from Jonah on anxious inquiry into his history, would alarm them the more, as implying the increasing nearness and certainty of their doom, and would at the same time reprove Jonah for his previous guilt in delaying to warn them. The very solitariness of the one message announced by the stranger thus suddenly appearing among them, would impress them with the more awe. Learning from him, that so far from lightly prophesying evil against them, he had shrunk from announcing a less severe denunciation, and therefore had been east into the deep and only saved by miracle, they felt how imminent was their peril, threatened as they now were by a prophet whose fortunes were so closely bound up with theirs. In Noah's days one hundred twenty years of warning were given to men, yet they repented not till the flood came, and it was too late. But in the case of Nineveh, God granted a double mercy: first, that its people should repent immediately after threatening; second, that pardon should immediately follow their repentance.”
