Here's some fascinating material on the functions of angels based on 
their linguistic meanings.  May be useful to those invoking angelic powers.
It's a little rough to read.  I pulled it off the NET a long time ago and 
may have posted it on the general list, but is useful nonetheless.

----------------------------------------------------------

Michael  -A militaristic guardian angel  (NIN-URTA)
Gabriel  -The governor of Eden           (NIN-LIL)
Uriel    -Ruler of all, surrounding Eden (EN-LIL)
Raphael  -Healing arts.                  (EN-KI)
Raguel   -Judging and monitoring
Sariel   -Punishment of crimes    (Ner-gal/Ninurta)
Remiel   -Responsible for spreading the word & news
 
As is readily apparent, all these names end with EL,
MICHA, MISH or MASH  (Michael) refers to
heroes in ancient Sumerian, as it does in Dravidian,
Ugrian, and ancient Scythian tongues. In Hungarian
stories the "heroes" are often called MISKA and hero
tales are also called MESHE. The heroic name refers
to  the military position    Michael as the guardian
and protector. The symbol of the hero is a serpent in
Sumerian, since it had a similar name, called MUSH.
In ancient cultures the serpent was often  a symbol
of rejuvenation, rebirth, healing as well as service
and wisdom. That is why the earliest Mesopotamian
art represented the mother goddess with a female
body and a serpent-like head. This tradition can be
traced also in Scythian legend .(see Naga, Boristenes)

GABR, GAVR  (Gabriel), was the female governor
of Eden. If we observe that the original Latin word
for governor, was "GUBERnator", then again the
ancient GABR title is recognized. Like many lan-
guages the B became V or was then deleted altogeth-
er, leaving KOR to be the root word for government
in Hungarian. According to Sumerian tradition, the
governor of Eden was often called Nin-Ti, "lady of
life" who was responsible for "genetic engineering"
in our modern vernacular. She was the Bau-dug-Gasan
"bountiful glad queen"  and Nin-Mah "great lady"
or as the wife of lord En-Lil she was called Nin-LIL,
who helped create 7 prototypes of Homo Sapiens
from combining genetic material from wild primitive
man and a compatible angel. She was also called the
lady of the mountain "Nin-Hursag", since Eden was
supposed to be located in a mountain valley. Since in
the Sumerian word Nin-Ti, "TI" also meant rib, the
later Babylonian translations of the "Lady of Life"
became "Lady of the Rib". It was this corruption of
her name which lead in time to the Biblical Eve to be
created from Adam's "rib". While other angels were
prone to have work in and out of their colony, Nin-
Lil's main responsibilities were in Eden. The GUB
root word in Sumerian means to stand or stay, while
GUBA meant to stand firm. (Hungarian Gubaszt).
 
UR name means guardian in Sumerian as well as
hero and lord. In the ancient Hurrian language of
norther Mesopotamia, the UR name became IUR
meaning "king". The Hurrians also spoke a
Ural-Altaic like agglutina  ve language, just as the
Sumerians and the Elamites. Similarly in ancient
Egyptian UR also meant king and kings were
considered by them to be of divine origin. In
Hungarian the lords or kings are also known as UR,
while guards are also called similarly O"R.
While the empty space above earth is also UR. This is
also similar to the Old Bulgar word "Ur-ugh", from
their original Hunnish language, before they were
absorbed by their Slavic subjects. Besides the title
UR the name of EN-LIL is completely understand-
able in Hungarian, since En was a title of lords, as in
the Hungarian pronoun "N today is the first person
pronoun of special respect. The word LIL refers to
air and breath in Sumerian as it does today in Hun-
garian Le'l-ek, Lelk, Lehel and so on. This is a
common word in the western Ural-Altaic languages.
The term LI in Sumerian however h d another
different meaning, which refered to life, and was
symbolized by a potted plant. That is why he was the
father of life and the soul/breath which animates the
material body. In Hungarian "Le'lek", refers to soul
and "E'l" refers to life, while "lehel" the breath. L"l
was also a name of one of the great lords, during the
Hungarian settlement in the 9th century. Several
Hungarian rulers of the seven tribes/nations also had
ancient Mesopotamian names. A'rpa'd/Egyptian Erpat,
Huba/Elamite Huba, Tohotom/Ancient Iranian Tehemtem,
On-d/Sumerian An, etc.)
 
RAG (from RAGUEL) was responsible with sen-
tencing or bringing to justice those who broke the
laws. In ancient Babylonian "RAGUMU" was t   suit
brought against the defendant. Simila ly in Hungarian
"RA'GA-lom" is the suit against the defendant. The
"lom" is just a  uffix of abstract concepts. In
Sumerian the RIG word, which is the source of
RAGUEL, simply meant to talk or speech, with
which a case is typically presented to a council.
Similarly REGE in Hungarian is a story given in
speech like sing song fashion, like a saga. It is also
related to the qualities of the voice (rikkan,rekedt).
In  old Hungarian the REGO"S were the bard  who sang
&  told stories of heroes and religion. The council of
elders, and the subject of knowledge they represented
in Sumerian is called TAN, just as in Hungarian and
several other Ural-Altaian languages, including even
Japanese. The decision which they brought f rward,
based on deliberation by a judge, is called BAR in
Sumerian as it is in Hungarian BIRO'. The word is
also found in a close eastern relative of the Hungari-
an language, the Chuvash,  s BAR. The word was
also adopted into English, through the influence of
the Huns. Even the remnant of the early Akkadian-
Babylonian word for lawyer UGIDU is found in
modern Hungarian U"gyve'd.
 
SAR (from SARIEL) is responsible with the punish-
ment of the guilty, the guardian of their imprisonment
who isolates the criminals and "encloses" them in a
penal holding area. In Sumerian the SAR wo d al o
means to enclose or encircle. Similarly SA means inner,
while SAG means inside. Sar also meant 3600 in
Sumerian,which was the closing of the circle and is
related tothe somewhat idealized period of 360 days in
a year. It was the Sumerians who first divided the
circle into 360 degrees.
Similarly in Hungarian ZA'R means lock
or enclose, while EZER also means a thousand.  The
old Ural-Altaic number system, unlike any others in
the world, was based on 6 and 60, like Sumerian, in
which the decimal places were in multiples of 6 or
60. That is why Hungarians still say "hatva'ny", when
expressing the idea of multiplying the effectiveness of
something. This word is derived from 60 (hatvan),
the ancient multiplier.
 
REM,REV (from REMIEL) is the most difficult of
functions to really characterize. He was supposed to
be the messenger and bringer of news and
information. However the root word REM is
normally associated with welcome, gladness,
happiness which is RU and DUG in Sumerian.
RA-GABA however means courier.  In English there
is a wonderful parallel word to this association, since
REVEL is to enjoy something but REVEAL is to
disclose hidd n information. Both of these words are
related to REM. These also associate with the
definition of Raphael discussed before. In Hungarian
"-R"M is also happiness, as in ancient Persian
RAMA. However ROV and IR in Hungarian is to
inscribe and write, which is important for sending
messages. The same word in Sumerian is SIR and
their scribes were called DUB-SAR. The bringing of
tidings and good news, was a cause of celebration
and good times it seems. Perhaps the following root
words  re also part of the name of SAR; IR=to
bring, RI=traverse (Hungarian Yar), MU=a ship or
vessel (Hungarian yar-M").
