John Gill's Exposition of the Whole Bible
Matthew 24:20
But pray ye that your flight be not in the winter,.... When days are short, and unfit for long journeys, and roads are bad, and sometimes not passable, through large snows, or floods of water; and when to dwell in desert places, and lodge in mountains, must be very uncomfortable: wherefore Christ directs to pray to God, who has the disposal of all events, and of the timing of them, that he would so order things in the course of his providence, that their flight might not be in such a season of the year, when travelling would be very difficult and troublesome. Dr. Lightfoot observes, from a Jewish writer h, that it is remarked as a favour of God in the destruction of the first temple, that it happened in the summer, and not in winter; whose words are these:
"God vouchsafed a great favour to Israel, for they ought to have gone out of the land on the tenth day of the month Tebeth; as he saith Ezekiel 24:2 "son of man, write thee the name of the day, even of this same day": what then did the Lord, holy and blessed? If they shall now go out in the winter, (saith he,) they will all die; therefore he prolonged the time to them, and carried them away in summer.''
And since therefore they received such a favour from him at the destruction of the first temple, there was encouragement to pray to him, that they might be indulged with the like favour when Jerusalem should be besieged again:
neither on the sabbath day: the word "day" is not in the Greek text; and some i have been of opinion, that the "sabbatical year", or the seventh year, is meant, when no fruits would be found in the fields, and a great scarcity of provisions among people; who would not have a sufficiency, and much less any to spare to strangers fleeing from their native places; but rather the sabbath day, or "day of the sabbath", as the Persic version reads it, is designed; and Beza says, four of his copies read it in the genitive case: and so four of Stephens's. And the reason why our Lord put them on praying, that their flight might not be on the sabbath day, was, because he knew not only that the Jews, who believed not in him, would not suffer them to travel on a sabbath day more than two thousand cubits; which, according to their traditions k, was a sabbath day's journey; and which would not be sufficient for their flight to put them out of danger; but also, that those that did believe in him, particularly the Jerusalem Jews, would be all of them fond of the law of Moses, and scrupulous of violating any part of it, and especially that of the sabbath; see Acts 21:20. And though the Jews did allow, that the sabbath might be violated where life was in danger, and that it was lawful to defend themselves against an enemy on the sabbath day; yet this did not universally obtain; and it was made a question of, after the time of Christ, whether it was lawful to flee from danger on the sabbath day; of which take the following account l.
"Our Rabbins teach, that he that is pursued by Gentiles, or by thieves, may profane the sabbath for the sake of saving his life: and so we find of David, when Saul sought to slay him, he fled from him, and escaped. Our Rabbins say, that it happened that evil writings (or edicts) came from the government to the great men of Tzippore; and they went, and said to R. Eleazar ben Prata, evil edicts are come to us from the government, what dost thou say? נברח, "shall we flee?" and he was afraid to say to them "flee"; but he said to them with a nod, why do you ask me? go and ask Jacob, and Moses, and David; as it is written, of Jacob, Hosea 12:12 "and Jacob fled"; and so of Moses, Exodus 2:15 "and Moses fled"; and so of David, 1 Samuel 19:18 "and David fled, and escaped": and he (God) says, Isaiah 26:20 "come my people, enter into thy chambers".''
From whence, it is plain, it was a question with the doctors in Tzippore, which was a town in Galilee, where there was an university, whether it was lawful to flee on the sabbath day or not; and though the Rabbi they applied to was of opinion it was lawful, yet he was fearful of speaking out his sense plainly, and therefore delivered it by signs and hints. Now our Lord's meaning, in putting them on this petition, was, not to prevent the violation of the seventh day sabbath, or on account of the sacredness of it, which he knew would be abolished, and was abolished before this time; but he says this with respect to the opinion of the Jews, and "Judaizing" Christians, who, taking that day to be sacred, and fleeing on it unlawful, would find a difficulty with themselves, and others, to make their escape; otherwise it was as lawful to flee and travel on that day, as in the winter season; though both, for different reasons, incommodious.
