Isaiah 66:15
12 For this is what the Lord says: “Look, I am ready to extend to her prosperity that will flow like a river, the riches of nations will flow into her like a stream that floods its banks. You will nurse from her breast and be carried at her side; you will play on her knees. 13 As a mother consoles a child, so I will console you, and you will be consoled over Jerusalem.” 14 When you see this, you will be happy, and you will be revived. The Lord will reveal his power to his servants and his anger to his enemies. 15 For look, the Lord comes with fire; his chariots come like a windstorm to reveal his raging anger, his battle cry, and his flaming arrows.
2 Thessalonians 1:8
5 This is evidence of God’s righteous judgment, to make you worthy of the kingdom of God, for which in fact you are suffering. 6 For it is right for God to repay with affliction those who afflict you, 7 and to you who are being afflicted to give rest together with us when the Lord Jesus is revealed from heaven with his mighty angels. 8 With flaming fire he will mete out punishment on those who do not know God and do not obey the gospel of our Lord Jesus. 9 They will undergo the penalty of eternal destruction, away from the presence of the Lord and from the glory of his strength, 10 when he comes to be glorified among his saints and admired on that day among all who have believed—and you did in fact believe our testimony.
Notes and References
"... the final (and decisive) allusion to Isaiah 66 can be found a bit later - and, again, the intertext can help us for a proper understanding of the passage in 2 Thessalonians: it is very difficult to determine the exact syntactical function of the phrase at the beginning of verse 8. Usually this words in the critical editions are connected to the passage before and seen as a further illustration of the 'revelation of the Lord Jesus' described in verse 7. In this case the text intends to say that the "revelation of the Lord Jesus" is going out from heaven, that he comes with the angels of his power and it takes place in a flame of fire ... While the words appear, for example, in Exodus 2:3 in the contexts of God's revelation in the burning bush, and while texts like the Revelation of Peter 5 connect parousia and the burning of the world, an intertextual connection to Isaiah 66:15 can help us to interpret the image in another way ... If we take our sub-text seriously, the parallel between 2 Thessalonians 1:8 and Isaiah 66:15 is not on the level of the Lord's coming 'in fire,' but on the idea that his judgement will take place in 'the flame of fire' - that's why the critical editions' comma should be deleted ..."
