The name Keziah is a girl's name of Hebrew origin meaning "cassia tree". Keziah and is often added to lists like Bible Names for Girls and discussed in our forums with posts like "The Makeover Baby Name Game".
From the experts:
Keziah, also spelled Kezia, is an Old Testament name — she was one of the three daughters of Job, about whom it was said that there were no women all the land who were so fair as Job's daughters — which was widely used for slaves and is still most common in the African-American community. The lovely, distinctive Keziah — along with others like her biblical sister Jemima — deserves full emancipation. Modern parents are also rediscovering the related, cinnamon-scented Cassia.
Some variations include Kezia, Kazia, Keshia, Kizzie, and Kizzy.
