'Alarm' in the Bible

Startled, and in the utmost alarm, they thought they were looking at a spirit;

but He said to them, "Why such alarm? And why are there such questionings in your minds?

For mark the effects of this very thing--your having sorrowed with a godly sorrow--what earnestness it has called forth in you, what eagerness to clear yourselves, what indignation, what alarm, what longing affection, what jealousy, what meting out of justice! You have completely wiped away reproach from yourselves in the matter.
