מִיָּמִ֣ים רַבִּים֮ תִּפָּקֵד֒ בְּאַחֲרִ֨ית הַשָּׁנִ֜ים תָּב֣וֹא ׀ אֶל־אֶ֣רֶץ ׀ מְשׁוֹבֶ֣בֶת מֵחֶ֗רֶב מְקֻבֶּ֙צֶת֙ מֵעַמִּ֣ים רַבִּ֔ים עַ֚ל הָרֵ֣י יִשְׂרָאֵ֔ל אֲשֶׁר־הָי֥וּ לְחָרְבָּ֖ה תָּמִ֑יד וְהִיא֙ מֵעַמִּ֣ים הוּצָ֔אָה וְיָשְׁב֥וּ לָבֶ֖טַח כֻּלָּֽם׃
After many days thou shalt be mustered for service, in the latter years thou shalt come against the land that is brought back from the sword, that is gathered out of many peoples, against the mountains of Israel, which have been a continual waste; but it is brought forth out of the peoples, and they dwell safely all of them.
Sifrei Devarim
R. Shimon b. Yochai says: Now if of those of whom "quickly" (i.e., "and you will go lost quickly") was written, were exiled only after the passage of much time (i.e., even though they were idolatrous for many years, they were not exiled until the days of Tzidkiyahu), how much more so (will this [long passage of time] obtain with) those (Gog, etc.), of whom "quickly" was not written, it being written (of them, Ezekiel 38:8) "After many years you will be remembered (for punishment)."
