'Avenges' in the Bible

for it is God's servant to you for what [is] good. But if you do what [is] bad, be afraid, because it does not bear the sword to no purpose. For it is God's servant, the one who avenges for punishment on the one who does [what is] bad.

not to transgress and to exploit his brother in the matter, because the Lord [is] the one who avenges concerning all these [things], just as also we told you beforehand and testified solemnly.
