II Thessalonians 1:6-8

⁶For after all it is only just for God to repay with affliction those who afflict you, ⁷and to give relief to you who are afflicted and to us as well when the Lord Jesus will be revealed from heaven with His mighty angels in flaming fire, ⁸dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus.
