“And it came to passe in those dayes, when there was no King in Israel, that there was a certaine Leuite soiourning on the side of mount Ephraim, who tooke to him a concubine out of Bethlehem Iudah.”
1611 King James Version (KJV)
19:1 A. concubine - Heb. a wife, a concubine, that is, such a concubine as was also his wife: called a concubine, only because she was not endowed. Perhaps he had nothing to endow her with, being himself only a sojourner.
