John Lightfoot on Matthew 24:20

[That your flight be not in the winter.] R. Tanchum observes a favour of God in the destruction of the first Temple, that it happened in the summer, not in winter. For thus he: "God vouch-safed 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, 'Son of man, mark this day; for on this very day,' &c. 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."
