Many are familiar with Yahweh. Yahweh is an English rendition of . "" is Hebrew, and those four letters, , are often called the Tetragrammaton. In English, "" is usually transliterated as YHWH. Traditionally, observant Jews do not say this name aloud, as it is believed to be too sacred to be uttered. Usually, euphemisms are used when referring to the name of GOD. These euphemisms include HaShem ("The Name") and Shem HaMeforash ("the ineffable Name."). In Hebrew, Yahweh literally means "I AM". We're familiar with this from Exodus:

And Moses said unto God, Behold, when I come unto the children of Israel, and shall say unto them, The God of your fathers hath sent me unto you; and they shall say to me, What is his name? what shall I say unto them? And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you.

Exodus 3:13-14 KJV
