Raguel is almost always referred to as the archangel of justice, fairness, harmony, vengeance and redemption. He is also sometimes known as the archangel of speech. In the Book of Enoch, cap. XXIII, Raguel is one of the seven angels whose role is to watch. His number is 6, and his function is to take vengeance on the world of the luminaries who have transgressed God's laws.
Raguel's duties have remained the same across Jewish and Christian traditions. Much like a sheriff or constable, Raguel's purpose has always been to keep fallen angels and demons in check, delivering judgment upon any that over-step their boundaries. He has been known to destroy wicked spirits, and cast fallen angels into Hell (called Gehenna in the Hebrew Old Testament and called Tartarus in the Greek New Testament).
Raguel is not mentioned in the canonical writings of the Bible. However, in 2 Enoch, which is generally considered non-canonical, the patriarch Enoch was carried as a mortal to and from Heaven by the angels Raguel and Sariel.
Possible historical references to a similar figure from other cultures can be found in Babylonian culture as "Rag" (some translations say Ragumu), and in Sumerian as "Rig" which means to talk or speech. Thus, these similar characters represented balance in those cultures as well.
