Now no scripture is of any private interpretation. You know a matter has to be established in the mouth of two or three witnesses.
Could you please provide a seconding scripture to this. So we can know the actual context of this generation as used by the Lord?
Easy:
(Mat 11:16 KJV)
But whereunto shall I liken this generation? It is like unto children sitting in the markets, and calling unto their fellows,
(Mat 11:17 KJV) And saying, We have piped unto you, and ye have not danced; we have mourned unto you, and ye have not lamented.
(Mat 11:18 KJV) For John came neither eating nor drinking, and they say, He hath a devil.
(Mat 11:19 KJV) The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.

(Mat 23:35 KJV) That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar.
(Mat 23:36 KJV) Verily I say unto you,
All these things shall come upon this generation.
(Mat 23:37 KJV) O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not!

(Mat 12:42 KJV) The queen of the south shall rise up in the judgment
with this generation, and shall condemn it: for she came from the uttermost parts of the earth to hear the wisdom of Solomon; and, behold, a greater than Solomon is here.
