'Queens' in the Bible

There are threescore queens, and fourscore concubines, And virgins without number.

My dove, my undefiled, is but one; She is the only one of her mother; She is the choice one of her that bare her. The daughters saw her, and called her blessed; Yea , the queens and the concubines, and they praised her.

And kings shall be thy nursing fathers, and their queens thy nursing mothers: they shall bow down to thee with their faces to the earth, and lick the dust of thy feet; and thou shalt know that I am Jehovah; and they that wait for me shall not be put to shame.
