'Avenged' in the Bible

And when he saw one [of them] being treated unfairly, he defended the oppressed man and avenged him by striking and killing the Egyptian.

because His judgments are true and righteous. He has judged [convicted and pronounced sentence on] the great prostitute (idolatress) who was corrupting and ruining and poisoning the earth with her adultery (idolatry), and He has imposed the penalty for the blood of His bond-servants on her.”
