[8:31]  ¹ 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).

[8:31]  ² sn The name Abimelech means “my father is king.”

[9:34]  ³ tn Heb “and all the people who were with him arose.”

[9:34]  ⁴ tn Heb “four heads.” The words “they divided into” are supplied in the translation for clarification.

[9:41]  ⁵ tc Heb “stayed.” Some scholars revise the vowel pointing on this verb from that of the MT, resulting in the translation “and he returned to.” The Lucianic recension of the LXX understands the word in this way.

[9:41]  ⁶ tn Heb “drove…out from dwelling in Shechem.”
