No, he did NOT specifically tell His then-present audience to leave. He said, "WHEN you see...", which THAT audience did NOT see. And Jesus preserved those words to this day. Had those events already occurred, there'da been no need for Him to have preserved them for us.
OTOH, YOU are ignoring MUCHO Scripture, beginning with Matt. 24:29-30, and virtually all the prophecies of Revelation, not to mention 2 Thess. 2:4, much of Daniel 9 & 11, and Luke 21.
Deny it all ya want, but you're still presenting pret garbage, phony as a Chevy Mustang!
