'Avenge' in the Bible

Won't God avenge his chosen ones, who are crying out to him day and night, and yet he exercises patience with them?

I tell you that he will avenge them quickly. Nevertheless, when the Son of Man comes, will he find faith on the earth?"

and being in readiness to avenge all disobedience, when your obedience will be made full.

They cried with a loud voice, saying, "How long, Master, the holy and true, until you judge and avenge our blood on those who dwell on the earth?"
