A.T. Robertson Commentary Matthew 28:8

"And they departed quickly from the tomb with fear and great joy, and ran to bring his disciples word." — Matthew 28:8 (ASV)

With fear and great joy (μετα φοβου κα χαρας μεγαλης). A touch of life was this as the excited women ran quickly (ταχυ εδραμον) as they had been told "to bring his disciples word" (απαγγειλα τοις μαθηταις αυτου). They had the greatest piece of news that it was possible to have. Mark calls it fear and ecstasy. Anything seemed possible now. Mark even says that at first they told no one anything for they were afraid , the tragic close of the text of Mark in Aleph and B, our two oldest manuscripts. But these mingled emotions of ecstasy and dread need cause no surprise when all things are considered.
