Gabriel appears most commonly in Jewish texts. He is one of at least seven archangels, or focal angels, who are known in liturgy and biblical commentary to be the highest or most powerful of the angelic legions.
In the pseudepigraphal Book of Enoch, Gabriel is an avenging angel, sent to incite sinners into war. In the Talmud (Sanhedrin 95b), God sends Gabriel to smite the Assyrians, and Gabriel replies that his sword "has been sharpened since the six days of Creation." In other words, he was in some way created to be an avenging angel.
