See also: D&C 132:1 

Concubine, a word commonly used in the Old Testament, was defined by Elder Bruce R. McConkie as follows:  “Anciently they were considered to be secondary wives, that is, wives who did not have the same standing in the caste system then prevailing as did those wives who were not called concubines.  There were no concubines connected with the practice of plural marriage in this dispensation, because the caste system which caused some wives to be so designated did not exist.”  (Mormon Doctrine, pp. 154–55) Doctrine and Covenants Student Manual, p. 327
