'Terror' in the Bible

But when they saw Him walking on the sea, they thought it was a ghost, and cried out [in horror];

He took Peter and James and John with Him, and He began to be deeply distressed and troubled [extremely anguished at the prospect of what was to come].

Entering the tomb, they saw a young man sitting on the right, wearing a [long, stately] white robe; and they were amazed and bewildered.
