Keturah (Hebrew: קְטוּרָה, Qəṭūrā, possibly meaning "incense";[1] Arabic: قطورة) was a wife[2] and a concubine[3] of the Biblical patriarch Abraham.

(Sumerians story say son of Shem, the priest lineage)[4] One modern commentator on the Hebrew Bible has called Keturah "the most ignored significant person in the Torah".

[3] Additionally, she is mentioned in Antiquities of the Jews by the 1st-century Romano-Jewish historian Josephus,[7] in the Talmud, the Midrash, the Targum on the Torah, the Genesis Rabbah, and various other writings of Jewish theologians and philosophers.

[8] Louis Feldman has said "Josephus records evidence of the prolific non-Jewish polymath Alexander Polyhistor, who in turn cites the historian Cleodemus Malchus, who states that two of the sons of Abraham by Keturah joined Heracles' campaign in Africa, and that Heracles, without doubt the greatest Greek hero of them all, married the daughter of one of them.

"[9] According to Doctor of Anthropology Paula M. McNutt, it is generally recognized that there is nothing specific in the biblical traditions recorded in Genesis, including those regarding Abraham and his family, that can be definitively related to known history in or around Canaan in the early second millennium B.C.

According to one opinion in the midrashic work Genesis Rabbah, Keturah and Hagar are names for the same person, whom Abraham remarried after initially expelling.
