'Vengeance' in the Bible

because these are days of vengeance to fulfill all the things that are written.

Friends, do not avenge yourselves; instead, leave room for His wrath. For it is written: Vengeance belongs to Me; I will repay, says the Lord.

taking vengeance with flaming fire on those who don’t know God and on those who don’t obey the gospel of our Lord Jesus.

For we know the One who has said, Vengeance belongs to Me, I will repay, and again, The Lord will judge His people.
