2 Chronicles 11:21

sn Concubines were slave women in ancient Near Eastern societies who were the legal property of their master, but who could have legitimate sexual relations with their 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).
