Malachi 3:5-6

5“Then I will come near you for judgment; I will be a swift witness against sorcerers, against adulterers, against perjurers, and against those who oppress the laborer in his wages and widows and the fatherless, and against those who turn away the alien [from his right], and those who do not fear Me [with awe-filled reverence],” says the Lord of hosts.

6“For I am the Lord, I do not change [but remain faithful to My covenant with you]; that is why you, O sons of Jacob, have not come to an end.
