1 Chronicles 1:32
1:32 The sons to whom Keturah, Abraham’s concubine,14 gave birth:
Zimran, Jokshan, Medan, Midian, Ishbak, Shuah.
The sons of Jokshan:
Sheba and Dedan.
sn A concubine was a slave woman in ancient Near Eastern societies who was the legal property of her master, but who could have legitimate sexual relations with her master. A concubine’s status was more elevated than a mere servant, but she was not free and did not have the legal rights of a free wife. The children of a concubine could, in some instances, become equal heirs with the children of the free wife. After the period of the Judges concubines may have become more of a royal prerogative (2 Sam 21:10–14; 1 Kgs 11:3).
