In Abrahamic religions, Gabriel ("Master, of God", i.e., a Master, who is "of God") is an archangel who is thought to serve as a messenger from God. "Angel" literally translates to "messenger" from the Koine Greek; an "arch" angel is a "primary" or "chief" messenger. He first appears in the Book of Daniel in the Hebrew Bible. He was also referred to as the "Left Hand of God".
Christians believe him to have foretold the births of John the Baptist and Jesus. In Islam, he is thought to have been the medium through which God revealed the Qur'an to Muhammad.
In biblical tradition, he is sometimes regarded as the angel of death, the prince of fire and thunder, but more frequently as one of God's chief messengers, and traditionally said to be the only angel that can speak Syriac and Chaldee. In Islam, Gabriel is one of God's chief messengers but other above mentioned titles are not given to him
In the Catholic Tradition, he is known as one of the archangels. In Islam, he is called the chief of the four favoured angels and the spirit of truth, and in some views Gabriel is the same person as the Holy Spirit.
1. In Latter-day Saint theology, Gabriel lived a mortal life as the patriarch Noah. Gabriel and Noah are regarded as the same person, but Gabriel alone is regarded as the immortal resurrected being (angel). As such, all of Noah's children are considered to be Gabriel's earthly children.
2. Gabriel the Arch-Angel of death is Azrael.
