And straightway all the people, when they beheld him, were greatly amazed, and running to him saluted him.

And he taketh with him Peter and James and John, and began to be sore amazed, and to be very heavy;

ἐκθαμβεῖσθαι ekthambeisthai “to be greatly awe-struck”

And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.

ἐξεθαμβήθησαν. exethambēthēsan “they were greatly amazed.”

And he saith unto them, Be not affrighted: Ye seek Jesus of Nazareth, which was crucified: he is risen; he is not here: behold the place where they laid him.

ἐκθαμβεῖσθε. ekthambeisthe “do be amazed.”
