'Avenging' in the Bible

And now, my lord, as Jehovah liveth, and as thy soul liveth, seeing Jehovah has restrained thee from coming with bloodshed, and from avenging thyself with thine own hand, now let thine enemies, and they that seek evil to my lord, be as Nabal.

And blessed be thy discernment, and blessed be thou, who hast kept me this day from coming with bloodshed, and from avenging myself with mine own hand.

Wherefore should the nations say, Where is their God? Let the avenging of the blood of thy servants that is shed be known among the nations in our sight.

A jealous and avenging God is Jehovah: an avenger is Jehovah, and full of fury: Jehovah taketh vengeance on his adversaries, and he reserveth wrath for his enemies.
