Answer:

"We are bound to thank God always for you, brethren, as it is fitting, because your faith grows exceedingly, and the love of every one of you all abounds toward each other, so that we ourselves boast of you among the churches of God for your patience and faith in all your persecutions and tribulations that you endure, which is manifest evidence of the righteous judgment of God, that you may be counted worthy of the kingdom of God, for which you also suffer; since it is a righteous thing with God to repay with tribulation those who trouble you, and to give you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels, in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ. These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power, when He comes, in that Day, to be glorified in His saints and to be admired among all those who believe, because our testimony among you was believed" (II Thessalonians 1:3-10).

In verse 9, the Greek text just says "from." It doesn't say "away from" or "coming from." The general view is that "from" is being used in the sense of "away from" because it is being contrasted with Jesus coming among those who believe. See Matthew 25:41. But the Greek is vague enough to include the fact that this banishment is coming from God Himself, so both senses can be true at the same time. What I was unable to find was anyone arguing that this statement is exclusively meaning "coming from" and doesn't include "away from."
