John Lightfoot on Mark 13:7

[Be not troubled.] Think here, how the traditions of the scribes affrighted the nation with the report of Gog and Magog, immediately to go before the coming of the Messiah:--

"R. Eliezer Ben Abina saith, When you see the kingdoms disturbing one another, then expect the footsteps of the Messiah. And know that this is true from hence, that so it was in the days of Abraham; for kingdoms disturbed one another, and then came redemption to Abraham." And elsewhere; "So they came against Abraham, and so they shall come with Gog and Magog." And again, "The Rabbins deliver. In the first year of that week [of years] that the Son of David is to come, shall that be fulfilled, 'I will rain upon one city, but I will not rain upon another,' Amos 4:7. The second year, the arrows of famine shall be sent forth. The third, the famine shall be grievous, and men and women and children, holy men, and men of good works, shall die. And there shall be a forgetfulness of the law among those that learn it. The fourth year, fulness, and not fulness. The fifth year, great fulness; for they shall eat and drink and rejoice, and the law shall return to its scholars. The sixth year, voices. (The Gloss is, 'A fame shall be spread, that the Son of David comes,' or, 'they shall sound with a trumpet.') The seventh year, wars; and in the going out of that seventh year the Son of David shall come."
