...couldn't provide a scripture refernce, but I'm referring to Jesus comment that "Some of you here present today will see the [end times]" (someone here will find the verse and line)
Jesus was referring to the coming astrological alignment (a "Shenkinah": helical rising of Mercury and Venus on the equinox) that would lead the Jews to rise up in a violent (failed) revolt in 70 AD. This revolt was crushed by Titus and lead to the diaspora.
Can't say I've heard your version of things there.
Are you talking about verses like:
Matthew 16:28 "I tell you the truth, some who are standing here will not taste death before they see the Son of Man coming in his kingdom."
It's interesting you reference "Shenkinah" (did you mean "Shekinah?") as the above verse is usually thought to be referring to the "Transfiguration."
Matthew 17:1-5The Transfiguration After six days Jesus took with him Peter, James and John the brother of James, and led them up a high mountain by themselves. There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light. Just then there appeared before them Moses and Elijah, talking with Jesus.
Peter said to Jesus, "Lord, it is good for us to be here. If you wish, I will put up three shelters—one for you, one for Moses and one for Elijah."
While he was still speaking, a bright cloud enveloped them, and a voice from the cloud said, "This is my Son, whom I love; with him I am well pleased. Listen to him.
She·ki·nah (sh-kn, --, -k-)

Sorry if that's not the type of verse to which you're referring....
