Because of the detailed nature of the below graphics, they will take a while to load unless you are on a fast connection. Below are 2 examples of where the Tetragrammaton has been found in ancient copies of the Septuagint. The Septuagint is a 3rd to 2nd Century BCE Greek translation of the Hebrew Scriptures. The below fragments are evidence that the Septuagint originally contained the name Yahweh.  

The first is an ancient fragment of the Septuagint dated between 50 BCE and 50 CE (AD). If this dating is correct, it would have been written near the time of Yahushua’s ministry. The name of these fragments are “Nahal Hever Minor Prophets” because they are fragments of Jonah, Micah, Nahum, Habakkuk, Zephaniah and Zechariah found in the Nahal Hever cave, south of Qumran. The Tetragrammaton is indicated with the large black arrow. 

Notice that the Tetragrammaton is written in the ancient Hebrew (Paleo-Hebrew) script. Here is another example of an ancient fragment of the Septuagint dating to the First Century CE (AD). This fragment contains parts Job 42:

There are other early fragments that also contain the sacred name in like manner. According to scholars, no copies of the Septuagint dated before the mid-2nd century CE/AD substitutes the Tetragrammaton (Yahweh’s name) with “Kyrios” (the Greek word Lord). 

This is a photo of Psalms 119:59-64 in the Dead Sea Scrolls which are a collection of Hebrew Scriptures that date back 2000 years. Note Yahweh’s name in the ancient Hebrew script while the rest of the text is in a more modern Hebrew that was used at the time. Also note that each line begins with the Hebrew letter “Heth” which corresponds with it’s part in the acrostical 119th psalm.

Compare this to the Masoretic Hebrew Text:

Now in English

Psalms 119:56-64
(NKJV)
59 I thought about my ways, And turned my feet to Your testimonies.
60 I made haste, and did not delay To keep Your commandments.
61 The cords of the wicked have bound me, [But] I have not forgotten Your law.
62 At midnight I will rise to give thanks to You, Because of Your righteous judgments.
63 I [am] a companion of all who fear You, And of those who keep Your precepts.
64 The earth, O , is full of Your mercy; Teach me Your statutes.

Some Christians, especially Jehovah’s witnesses, use this name for the Heavenly Father. However, every scholar and every reference book I have ever checked on "Jehovah" (including Jehovah’s witness tracts) has said that this is not the way you pronounce His name! First of all it is impossible because of the fact that the Hebrew language has no "J" sound!

According to the Encyclopedia Britannica, 1991 under the heading "Yahweh", here is how this name came into being:

"The Masoretes, who from about the 6th to the 10th century worked to reproduce the original text of the Hebrew Bible, replaced the vowels of the name YHWH with the vowel signs of the Hebrew word Adonai or Elohim. Thus the artificial name Jehovah (YeHoWaH) came into being."

So we see here one of many confirmations that the name Jehovah is not really His name at all! But it is a artificial name that was invented by man. Does man have the right to change the name of the one who created him? I think not! But that is exactly what has happened here.

Now let’s look a little more deeply into this name Jehovah. Notice that many Hebrew names contain the first part of Yahweh’s name which is Yah. This is true in the name Isa-YAH (Hebrew: YeshaYAH), which means "Yah is Salvation". Also in Jeremi-Yah (Hebrew: YermeYAH), Obadiah, Zechariah, and so on. Taking this knowledge, apply this to the name Je-hovah with Jeh being the first part of His name. First of all it doesn’t add up when it comes to the names of these prophets. (Isaiah’s name isn’t IsaJEH) Second, the Hovah part of Je-hovah means RUIN and MISCHIEF in Hebrew according to Strong’s Concordance #1943:

#1943 Hovah, another form for 1942; RUIN:-MISCHIEF

This is a very common question. It all began with a Jewish tradition called the “ineffable name” doctrine. Jews, for various reasons, started to substitute His name with the Hebrew title “Adonai”. Adonai is the Hebrew word for "Lord". This information can be easily verified in many Bible dictionaries and various encyclopedias. For instance, the Encyclopedia Britannica states:

Yahweh, the God of the Israelites, his name being revealed to Moses as four Hebrew

CONSONANTS (YHWH) CALLED THE TETRAGRAMMATON. AFTER THE EXILE (6TH CENTURY BC), and especially from the 3rd century BC on, Jews ceased to use the name Yahweh for two reasons. As Judaism became a universal religion through its proselytizing in the Greco-Roman world, the more common noun elohim, meaning "god," tended to replace Yahweh to demonstrate the universal sovereignty of Israel’s God over all others. At the same time, the divine name was increasingly regarded as too sacred to be uttered; it was thus replaced vocally in the synagogue ritual by the Hebrew word Adonai ("My Lord"), which was translated as Kyrios ("Lord") in the Septuagint, the Greek version of the Old Testament.

We see in the above quote that Jews started to vocally replace the name "Yahweh" with "Adonai" (Lord) for two reasons:

1. It was beginning to be believed that His name was too sacred to be uttered

2. They preferred to simply call Him "Elohim" rather than "Yahweh" to demonstrate to the world that He is the only true Elohim.

While on the surface these reasons may seem honorable, they are very unscriptural. They were and are attempts to improve on Yahweh’s already perfect ways. If Yahweh really wanted a substitute, why would He have placed His name there to begin with? Though scripture says to follow Yahweh rather than man, we find that nearly 7,000 times the most important name of all is replaced with a another word that man has chosen. 

This tradition was not practiced by the Messiah or the apostles, but it was adopted by some Christians during the early half of the 2nd Century CE/AD. By the 4th century, this practice was well established and widely practiced. Jerome, a 4th century "Church Father" who authored the Latin Vulgate version, substituted the name "Yahweh" throughout with the Latin word "Dominus" (meaning "Lord"). The tradition of replacing Yahweh’s name with “the Lord” continues to this day. Most English translations substitute the name Yahweh with “the LORD" and translations into other languages will also commonly choose a title meaning "Lord" in their own language. More information on this can be found in the preface of many modern bibles.

This is a question that is often asked. Why should an English speaking
person call on the Hebrew names of Yahweh and Yahushua?

The answer is actually quite simple. Personal names do not translate across languages. For instance, Ariel Sharon is still Ariel Sharon in any country or language.  Personal names do not translate, they transliterate. In other words, they retain the pronunciation as much as possible. Even so, "The LORD" is not a translation of the name "Yahweh". It is a direct replacement. Put simply, the translators admit they substituted Yahweh’s name for a title. All for the sake of an unscriptural tradition. Yahweh’s name is in scripture nearly 7000 times. And nearly 7000 times they replaced it (not translated it) with "the LORD", or "GOD". I wouldn’t want someone to change my name unless it was Yahweh. And it is clear that according to the third commandment that Yahweh doesn’t want anyone to change or falsify His name either. 

Think about this for a moment. What makes man think he has the authority to change the name of the one who created him, and who created all things? We don’t have that right! For instance, in the scriptures we see that one who changes the name of another is always in authority over them. Yahushua renamed Simon. Yahweh renamed Abram to Abraham. Adam named the animals. We have no authority to rename our Heavenly Father or His Messiah Yahushua. We need to be sure we leave things as He inspired it.

Also consider this: If you don’t speak Hebrew then you can’t say Abraham, Isaac, Isaiah, Ezekiel, Obadiah, Zechariah, Michael or a long list of other Hebrew names! Why was Yahweh’s name the only one changed? And why was Yahushua’s Name the only name in our modern bibles that is different from the Old Testament to the New Testament? In the Old Testament, it’s "Joshua" but in the New Testament it’s "Jesus". The answer is simple. Satan will do anything to turn men from the truth. Yahweh’s Name IS truth. Yahushua’s Name IS truth. Substitutions are lies. You see, Father Yahweh is seeking those who worship Him in spirit and in truth. And when we call Him by a false name, then we are worshipping Him in lies and not truth. If we know that "the Lord" and "Jesus" are false, why continue in error?? Aren’t we supposed to love the truth?

But maybe you are thinking, "Okay so do you have any scriptures that show that Gentiles should be calling on His name?" I am glad you asked….
