Luke 9:31

His decease - Την εξοδον αυτον, That going out (or death) of his. That peculiar kind of death - its nature, circumstances, and necessity being considered. Instead of εξοδον, thirteen MSS. have δοξαν, glory. They spoke of that glory of his, which he was about to fill up (πληρουν) at Jerusalem. The Ethiopic unites both readings. The death of Jesus was his glory, because, by it, he gained the victory over sin, death, and hell, and purchased salvation and eternal glory for a lost world.

In glory - Of a glorious appearance. Of an appearance like that which the saints have in heaven.

His decease - literally, his "exit" or "departure." The word translated here "decease" - that is, exit, or "going out" - is elsewhere used to denote death. See 2 Peter 1:15. Death is a departure or going out from this life. In "this" word there may be an allusion to the "departure" of the children of Israel from Egypt. As that was going out from "bondage," pain, and humiliation, so death, to a saint, is but going forth from a land of captivity and thraldom to one of plenty and freedom; to the land of promise, the Canaan in the skies.

He should accomplish - Which was about to take place.

9:31 In glory - Like Christ with whom they talked.
