The name of Abraham's wife after Sarah died, mother of six sons who became Arabian tribal ancestors. Genesis 25:1, 4 record her marriage to Abraham and her descendants. First Chronicles 1:32-33 parallel this genealogy, though there she is called a concubine rather than wife. The name may derive from a root meaning 'incense' (קְטֹרֶת), possibly suggesting 'perfumed one' or 'incense woman,' though this is uncertain. Through Keturah's sons, Abraham became the father of numerous Arabian peoples.
