Angel

An angel is a purely spiritual being found in various religions and mythologies. In Abrahamic religions and Zoroastrianism, angels are often depicted as benevolent celestial beings who act as intermediaries between God or Heaven and Earth, or as guardian spirits or a guiding influence. Other roles of angels include protecting and guiding human beings, and carrying out God's tasks. The term "angel" has also been diversed to various notions of spirits or figures found in many other religious traditions. The theological study of angels is known as "angelology".

In art, angels are often depicted with bird-like wings on their back, a halo, robes and various forms of glowing light.

Etymology

The word angel (pronounced /ˈeɪn.dʒəl/) in English is a blend of Old English engel (with a hard g) and Old French angele. Both derive from Late Latin angelus "messenger", which in turn was borrowed from Late Greek ἄνγελος ángelos. According to R. S. P. Beekes, ángelos itself may be "an Oriental loan, like ἄγγαρος ['Persian mounted courier']." The word's earliest form is Mycenaean a-ke-ro attested in Linear B syllabic script.

Federal Bureau of Investigation

The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States, which simultaneously serves as the nation's prime Federal law enforcement organization. Operating under the jurisdiction of the U.S. Department of Justice, FBI is concurrently a member of the U.S. Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U.S. counterterrorism, counterintelligence, and criminal investigative organization, FBI has jurisdiction over violations of more than 200 categories of federal crimes.

Although many of FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection overseas, FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in lesser cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Director of National Intelligence.
