Malachi 3:5

And I will come near to you for judging; I will quickly be a witness against the wonder-workers, against those who have been untrue in married life, against those who take false oaths; against those who keep back from the servant his payment, and who are hard on the widow and the child without a father, who do not give his rights to the man from a strange country, and have no fear of me, says the Lord of armies.
