John Gill Commentary Mark 10:37

"And they said unto him, Grant unto us that we may sit, one on thy right hand, and one on [thy] left hand, in thy glory." — Mark 10:37 (ASV)

They said unto him
By their mother, or seconding her motion:

grant unto us that we may sit, one on thy right hand, and the other
on thy left hand, in thy glory ;
or glorious kingdom, which they expected would be quickly set up; and which they might conclude from his having lately promised to all the twelve, that when he should sit on his throne, they should sit on twelve thrones, judging the twelve tribes of Israel; and from his having just now mentioned his rising from the dead, which they might understand of some revival, or breaking forth of this glorious state; (See Gill on Matthew 20:21).
