Being inscrutable does not contrary to the Holy Spirit characteristically noting exceptions to the norm (from age to bed size to sinlessness) among even lesser characters and exceptional wickedness of principle ones. The problem is with what you see, that of Solomon's multiple wives (common among kings, incldng. David), with the religion of foreigners being what is pointedly described, while you read into this that which includes unprecedented sexual deviancy. Simply unwarranted presumption.
Suit yourself.
