Malachi 3:5-6

5At that time, I will come among you as your judge. I will speak clearly against those who have done wrong things. I will punish the magicians, the adulterers and those who tell lies against other people. I will punish those people who are cruel to their workers, or they deceive widows or children who have no family. And I will punish those who do not help foreigners who live among them. People who do those things show that they do not respect me.’ That is what the Lord Almighty says.

6‘I am the Lord and I do not change. Because of my promises to my people, I have not destroyed you, descendants of Jacob.
