G1568–ἐκθαμβέω–ekthambeō

Immediately the whole multitude on beholding Him were astonished and awe-struck, and yet they ran forward and greeted Him.

ἐξεθαμβήθησαν exethambēthēsan “they marvelled”

Then He took with Him Peter and James and John, and began to be full of terror and distress,

ἐκθαμβεῖσθαι ekthambeisthai “to be greatly awe-struck”

Upon entering the tomb, they saw a young man sitting at their right hand, clothed in a long white robe. They were astonished and terrified.

ἐξεθαμβήθησαν. exethambēthēsan “they were greatly amazed.”

But he said to them, "Do not be terrified. It is Jesus you are looking for--the Nazarene who has been crucified. He has come back to life: He is not here: this is the place where they laid Him.

ἐκθαμβεῖσθε. ekthambeisthe “do be amazed.”
