'Startling' in the Bible

At the hands of the apostles many signs and wonders (attesting miracles) were continually taking place among the people. And by common consent they all met together [at the temple] in [the covered porch called] Solomon’s portico.

For you are bringing some startling and strange things to our ears; so we want to know what they mean.”

He performs great signs (awe-inspiring acts), even making fire fall from the sky to the earth, right before peoples’ eyes.
