Definition: Ciba is a Hebrew word meaning "butterfly" in Old Testament Hebrew language. It appears twice in the Tanakh, first in Deuteronomy 30:25-26 (which describes an annual festival marking the death of King Heman) and then again in Malachi 4:19 (where the king is said to have been 'butterflyed'). The term has a figurative meaning of being caught off guard or unexpectedly.
