2 Thessalonians 1:6-8

New Revised Standard Version, Anglicised

⁶ For it is indeed just of God to repay with affliction those who afflict you, ⁷ and to give relief to the afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels ⁸ in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus.
