Albert Barnes Commentary Mark 9:1

"And he said unto them, Verily I say unto you, There are some here of them that stand [by], who shall in no wise taste of death, till they see the kingdom of God come with power." — Mark 9:1 (ASV)

Verily I say, etc. See Barnes on Matthew 16:28.

This verse properly belongs to the preceding chapter, and the preceding discourse.
