Mark 9:11

And they asked him, saying ,.... Being put in mind of it, by seeing Elias on the mount, or else by what Christ had said concerning his resurrection, or both:

why say the Scribes , the Vulgate Latin adds, "and Pharisees",

that Elias must first come ? before the Messiah comes, or before the setting up his kingdom in greater glory; See Gill on Matthew 17:10 .
