1 Kings 11:3 New English Translation

³He had 700 royal wives^[a] and 300 concubines;^[b] his wives had a powerful influence over him.^[c]

1 Kings 11:3 tn Heb “wives, princesses.”
1 Kings 11:3 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. The usage in the present passage suggests that after the period of the Judges concubines may have become more of a royal prerogative (cf. also 2 Sam 21:10-14).
1 Kings 11:3 tn Heb “his wives bent his heart.”
