It may come as no surprise to the founders of the USA and Yahoo that the term Yahoo comes from the Hebrews being called “Yah-udim” - those belonging to “Yah” - Elohim.  

(They deny this - yet probably unwittingly then picked up the term from Jonathan Swift's Yahoo Race of People in Gulliver's Travels.)

It appears the name YHWH pre-date the Jewish Kabbal-istic doctrine.

In the book Fossilised Customs by Lew White; it’s the "Sinia Autograph" that God Himself signed following His Ten Commandments (Exo. 31:18)

The name YHWH is from four paleo/palaeo-Hebrew letters. Paleo/palaeo meaning both ‘ancient’ and ‘Hebrew’ and said to derive from one of Shem’s descendants; Eber (Gen. 10). Abram is a Hebrew (Gen. 14.)

Hebrew is the "Lashon Qodesh", or set-apart tongue. These four letters are known as a "Tetra gram" and there are many transliterations.

Though it seems the letters YHWH were changed to JHVH. Some took JHVH and placed the vowels from the word Adonai in between.

It was Petrus Galatinus who gave us the word Jehovah after the Spanish monk Raymond Mantini, translated about 1270 different parts of the Bible from the Hebrew. In his manuscripts on the right side is the Hebrew text and on the left the Latin with; “Iehovah”.

Cardinal Nikolaus of Kues used the Tetragrammaton vocalised as Jehovah in several of his works, 1428, in his Sermon In Principio Erat Verbum. Then in 1518 Petrus Galatinus published his work "De Arcnis catholicae veritatis".  As did William Tyndale, translate the Pentateuch in 1530, he transferred the Tetragrammaton also by using the word Jehovah.

Based on the JHVH tetra gram, the letter "J" never existed until about 1520 C.E.

Author Lew White says; '...the correct translation is; Ya-HOO'-ah.'

It's further claimed that when the Hebrews where in Babylonian captivity; the name was suppressed because of the blasphemy involved to that of the Babylonians.

The Hebrews were called "Yahudim" or those belonging to "YAH", their Elohim = "God" or "gods".

It said it was the Babylonians who called them "Yahoos", and rather than the Hebrews hear the name blasphemed that way they avoided it all together. It was over time that it became an offence worthy of death to speak it, except for the priest or Kohen.

In Act 7 - Stephen was stoned to death by Saul for using the name openly.

They say that the Hebrew word Elohim is a plural noun, showing that there is more than one God. This obviously upsets all those who believe in a singular God; - but note; in Genesis 1:26, God says, "Let ‘us’ make man in ‘our’ image." Whereas the other camp argue the Hebrew Bible plainly quotes God as saying that there is only one God. "I am God," he says, "and there is no other" (Isaiah 45:22).

And perhaps why we can see this instant division within the religious camps.

It is interesting to read the alleged word "Yahoo" for Yahoo Inc. is an acronym for; "Yet Another Hierarchical Officious Oracle".

The term "hierarchical" described how the Yahoo database was arranged in layers of subcategories. The term "oracle" was intended to mean "source of truth and wisdom", and the term "officious", rather than being related to the word's normal meaning, described the many office workers who would use the Yahoo database while surfing from work.

Filo and Yang insist they mainly selected the name because they liked the slang definition of a "Yahoo" (used by college students in David Filo's native Louisiana in the late 1980s and early 1990s to refer to an unsophisticated, rural Southerner): "rude, unsophisticated, uncouth."

Filo's college girlfriend often referred to Filo as a "Yahoo." This meaning derives from the Yahoo race of fictional beings from Gulliver's Travels; a novel by Anglo-Irish writer and clergyman Jonathan Swift.

Swift was a essayist, political pamphleteer - ‘Lobbyists‘ (first for the Whigs, then for the Tories), poet and cleric who became Dean of St Patrick's Cathedral, Dublin.  

Swift no doubt read works by Petrus Galatinus and alike.  Swift originally published all of his works under pseudonyms – such as Lemuel Gulliver, 'Isaac Bickerstaff', MB Drapier – or anonymously.

Isaac Bickerstaff Esq was a pseudonym used by as part of a hoax to predict the death of then famous Almanac–maker and astrologer John Partridge. “All Fools Day” (now known as April Fools Day which falls on 1 April) was Swift’s favourite of holidays and he often used this day to aim his satirically biting wit at non-believers in an attempt to “make sin and folly bleed.” Disgruntled by Partridge’s sarcastic attack about the “infallible Church” written in his 1708 issue of Merlinus Almanac, Swift projected carefully three letters and one Eulogy as an elaborate plan to “predict” Partridge’s “infallible death” to be revealed on April 1, All Fools Day.

So knowing of Swifts advanced knowledge of religion and literature in general - it has to be assumed he knew well who he was referring to when he wrote about the 'Yahoo race'; a Yahoo is a legendary being in Gulliver's Travels.

The Servants Drive a Herd of Yahoos into the Field by Louis John Rhead.

Swift described them as being filthy and with unpleasant habits, resembling human beings far too closely for the liking of protagonist Lemuel Gulliver, who finds the calm and rational society of intelligent horses, the Houyhnhnms, greatly preferable.

The Yahoos are primitive creatures obsessed with "pretty stones" they find by digging in mud, said to suggest representing the distasteful materialism and ignorant elitism Swift encountered in Britain.  

(This sounds like he is having a go at Paganism; - Stonehenge, the Merry Maiden stones etc. and makes you wonder; why is it that 'religious' folk such as Swift - frown-upon such ancient history?  Is it because they are a constant reminder that they proceed such works like that of the Bible?  It also may reflect Swifts religious beliefs and hatred towards the Jews for their Antichrist stance to Jesus and his crucifixion.) 

Hence the term "Yahoo" has come to mean "a crude, brutish or obscenely coarse person".

American frontiersman Daniel Boone, who often used terms from Gulliver's Travels, claimed that he killed a hairy giant that he called a Yahoo.

Yahoos were referred to in a letter sent by serial killer David Berkowitz to New York City police while committing the "Son of Sam" murders in 1976.

Ya'Hoo'ah! ;-)
