Malachi 3:5-7 New Revised Standard Version (NRSV)
5 Then I will draw near to you for judgment; I will be swift to bear witness against the sorcerers, against the adulterers, against those who swear falsely, against those who oppress the hired workers in their wages, the widow and the orphan, against those who thrust aside the alien, and do not fear me, says the Lord of hosts.
6 For I the Lord do not change; therefore you, O children of Jacob, have not perished. 7 Ever since the days of your ancestors you have turned aside from my statutes and have not kept them. Return to me, and I will return to you, says the Lord of hosts. But you say, “How shall we return?”
