No cherry picking at all, unless your the cherry picker lol.
I simply followed up on YOUR words --> "You forget that the same event is described in other references" of which I followed up, by supplying these other references following, where the Exact same subject, event is described.
You forget that the same event-->And he said unto them, Verily I say unto you, That there besomeof them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power. is described in other references -->Matt 16:28 -Verily I say unto you, There besomestanding here, which shall not taste of death, till they see the Son of man coming in the kingdom of Him Luke 9:27 - .But I tell you of a truth, there besomestanding here, which shall not taste of death, till they see the kingdom of God.
Well,....looky here, none of this -->where''all the tribes on earth''is clearly being stated, including descriptions of the event that all the tribesare to witness and a timeline for that to happen.--> to be found anywhere in these three repeatedreferences That is what you ignore.
