2 Thessalonians 1:6-10 NASB95
For after all it is [only] just for God to repay with affliction those who afflict you, and [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, dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus. These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power, when He comes to be glorified in His saints on that day, and to be marveled at among all who have believed--for our testimony to you was believed.
