G1568–ἐκθαμβέω–ekthambeō

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

ἐξεθαμβήθησαν exethambēthēsan “they marvelled”

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

ἐκθαμβεῖσθαι ekthambeisthai “to be greatly awe-struck”

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

ἐξεθαμβήθησαν. exethambēthēsan “they were greatly amazed.”

And he saith to them, Be not frightened: ye seek Jesus of Nazareth, who was crucified: he is risen; he is not here: behold the place where they laid him:

ἐκθαμβεῖσθε. ekthambeisthe “do be amazed.”
