(Exodus 3:11-15) However, Moses said to the true God: “Who am I that I should go to Pharʹaoh and bring the Israelites out of Egypt?” 12 To this he said: “I will prove to be with you, and this is the sign for you that it was I who sent you: After you have brought the people out of Egypt, you people will serve the true God on this mountain.” 13 But Moses said to the true God: “Suppose I go to the Israelites and say to them, ‘The God of your forefathers has sent me to you,’ and they say to me, ‘What is his name?’ What should I say to them?” 14 So God said to Moses: “I Will Become What I Choose to Become.” And he added: “This is what you are to say to the Israelites, ‘I Will Become has sent me to you.’” 15 Then God said once more to Moses: “This is what you are to say to the Israelites, ‘Jehovah the God of your forefathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.’ This is my name forever, and this is how I am to be remembered from generation to generation.



Quote: [Who else is there to for him to be mistaken for?]

Here are some names of some false gods that were common in the time of Moses:
The Ten Plagues. By means of the plagues he visited upon the Egyptians, Jehovah humiliated and executed judgment upon their gods. (Ex 12:12; Nu 33:4; PICTURES, Vol. 2, p. 530) The first plague, the turning of the Nile and all the waters of Egypt into blood, brought disgrace to the Nile-god Hapi. The death of the fish in the Nile was also a blow to Egypt’s religion, for certain kinds of fish were actually venerated and even mummified. (Ex 7:19-21) The frog, regarded as a symbol of fertility and the Egyptian concept of resurrection, was considered sacred to the frog-goddess Heqt. Hence, the plague of frogs brought disgrace to this goddess. (Ex 8:5-14) The third plague saw the magic-practicing priests acknowledging defeat when they proved to be unable by means of their secret arts to turn dust into gnats. (Ex 8:16-19) The god Thoth was credited with the invention of magic or secret arts, but even this god could not help the magic-practicing priests to duplicate the third plague.
The line of demarcation between the Egyptians and the worshipers of the true God came to be sharply drawn from the fourth plague onward. While swarms of gadflies invaded the homes of the Egyptians, the Israelites in the land of Goshen were not affected. (Ex 8:23, 24) The next plague, the pestilence upon the livestock, humiliated such deities as the cow-goddess Hathor, Apis, and the sky-goddess Nut, who was conceived of as a cow having the stars affixed to her belly. (Ex 9:1-6) The plague of boils brought disgrace to the gods and goddesses regarded as possessing healing abilities, such as Thoth, Isis, and Ptah. (Ex 9:8-11) The severe hailstorm put to shame the gods who were considered to have control of the natural elements; for example, Reshpu, who, it appears, was believed to control lightning, and Thoth, who was said to have power over the rain and thunder. (Ex 9:22-26) The locust plague spelled defeat for the gods thought to ensure a bountiful harvest, one of these being the fertility god Min, who was viewed as a protector of the crops. (Ex 10:12-15) Among the deities disgraced by the plague of darkness were sun-gods, such as Ra and Horus, and also Thoth the god of the moon and believed to be the systematizer of sun, moon, and stars.—Ex 10:21-23.
The death of the firstborn resulted in the greatest humiliation for the Egyptian gods and goddesses. (Ex 12:12) The rulers of Egypt actually styled themselves as gods, the sons of Ra, or Amon-Ra. It was claimed that Ra, or Amon-Ra, had intercourse with the queen. The son born was, therefore, viewed as a god incarnate and was dedicated to Ra, or Amon-Ra, at his temple. Hence, the death of Pharaoh’s firstborn, in effect, actually meant the death of a god. (Ex 12:29) This in itself would have been a severe blow to Egypt’s religion, and the complete impotence of all the deities was manifested in their being unable to save the firstborn of the Egyptians from death.—See AMON No. 4.

Question: Are you really not aware that Gods name has been removed from most English translations? If so, I understand your inability to answer the question.

God also said to Moses, “Say to the Israelites, ‘The LORD, the God of your fathers—the God of Abraham, the God of Isaac and the God of Jacob—has sent me to you.’ “This is my name forever, the name you shall call me from generation to generation. 

You cannot prove a removal, by referencing the JW addition.]


'in exodus 3:15 most other versions of the bible say...'
I guess that answers this question of mine:
Question: Are you really not aware that Gods name has been removed from most English translations? If so, I understand your inability to answer the question.

I know what most other translations do. That's why I asked the question silly.

Check out these translations.

Try to stay on the subject.
Remember what we are discussing is rather or not translations have replaced God's name with titles like LORD and GOD, not rather or not you are a believer or rather a certain branch of Christianity have produced a version of the bible superior to all the other (earlier) versions.
Can you not tell me the names of the several that you have read?



EDIT: 
This guy says at his Lutheran Church they use the ESV.

So here is the prevace to the ESV:

The Translation of Specialized Terms

In the translation of biblical terms referring to God, the ESV takes great care to convey the specific nuances of meaning of the original Hebrew and Greek words. First, concerning terms that refer to God in the Old Testament: God, the Maker of heaven and earth, introduced himself to the people of Israel with a special personal name, the consonants for which are YHWH (see Exodus 3:14–15). Scholars call this the “Tetragrammaton,” a Greek term referring to the four Hebrew letters YHWH. The exact pronunciation of YHWH is uncertain, because the Jewish people considered the personal name of God to be so holy that it should never be spoken aloud. Instead of reading the word YHWH, they would normally read the Hebrew word ’adonay(“Lord”), and the ancient translations into Greek, Syriac, and Aramaic also followed this practice. When the vowels of the word ’adonay are placed with the consonants of YHWH, this results in the familiar word Jehovah that was used in some earlier English Bible translations. As is common among English translations today, the ESV usually renders the personal name of God (YHWH) with the word Lord (printed in small capitals). An exception to this is when the Hebrew word ’adonay appears together with YHWH, in which case the two words are rendered together as “the Lord [in lowercase] God [in small capitals].” In contrast to the personal name for God (YHWH), the more general name for God in Old Testament Hebrew is ’elohim and its related forms of ’el or ’eloah, all of which are normally translated “God” (in lowercase letters). The use of these different ways to translate the Hebrew words for God is especially beneficial to English readers, enabling them to see and understand the different ways that the personal name and the general name for God are both used to refer to the One True God of the Old Testament.

Since in the first century God was one, how and when did he become three?
(Romans 3:30) Since God is one, he will declare circumcised people righteous as a result of faith and uncircumcised people righteous by means of their faith.

(Deuteronomy 6:4) “Listen, O Israel: Jehovah our God is one Jehovah.
(1 Corinthians 8:6) there is actually to us one God, the Father, from whom all things are and we for him; and there is one Lord, Jesus Christ, through whom all things are and we through him.
(Ephesians 4:6) one God and Father of all, who is over all and through all and in all.
