Jamieson, Fausset and Brown on Matthew 28:7

7. And go quickly, and tell his disciples--For a precious addition to this, see on Mr 16:7.

that he is risen from the dead; and, behold, he goeth before you into Galilee--to which those women belonged (Mt 27:55).

there shall ye see him--This must refer to those more public manifestations of Himself to large numbers of disciples at once, which He vouchsafed only in Galilee; for individually He was seen of some of those very women almost immediately after this (Mt 28:9, 10).

Lo, I have told you--Behold, ye have this word from the world of light!
