Mark 10:31

πολλοὶ δὲ ἒσονται. Lk. gives this Saying at an earlier point (Mark 13:30); it was probably uttered more than once, and it is capable of more than one application. Many who think that they have earned much will be disappointed, and many who think that they have earned little will be surprised, as the labourers in the vineyard. The fortunate and unfortunate will often change places, as Dives and Lazarus. “The greyhaired saint may fail at last,” as Judas, and the greyhaired sinner may be saved, as the penitent robber.
