3 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).
