John Lightfoot on Luke 23:30

[Then shall they begin to say to the mountains, &c.] So they do say, Revelation 6:6: from whence, among other arguments, it may be reasonably supposed, that that chapter treats of the plagues and afflictions that should forerun the destruction of Jerusalem, and, indeed, the destruction and overthrow itself. Weigh the place accurately; and perhaps thou wilt be of the same mind too. Nay, I may further add, that perhaps this observation might not a little help (if my eyes fail me not) in discovering the method of the author of the Book of the Revelation.
