Meaning and Derivation: Yahweh is the promised name of God. This name of God which (by Jewish tradition) is too holy to voice, is actually spelled "YHWH" without vowels. YHWH is referred to as the Tetragrammaton (which simply means "the four letters"). YHWH comes from the Hebrew letters: Yud, Hay, Vav, Hay. While YHWH is first used in Genesis 2, God did not reveal Himself as YHWH until Exodus 3. The modern spelling as "Yahweh" includes vowels to assist in pronunciation. Many pronounce YHWH as "Yahweh" or "Jehovah." We no longer know for certain the exact pronunciation. During the third century A.D., the Jewish people stopped saying this name in fear of contravening the commandment "Thou shalt not take the name of the LORD thy God in vain" (Exodus 20:7). As a result of this, Adonai is occasionally a substitute for YHWH. The following compound names which start with "YHWH" have been shown using "Jehovah." This is due to the common usage of "Jehovah" in the English of these compound names in the early English translations of the Bible (e.g., the Geneva Bible, the King James Version, etc.).

Commentary:
Here is a name given to the Creator which we have not yet met with, and that is Jehovah--the LORD, in capital letters, which are constantly used in our English translation to intimate that in the original it is Jehovah. All along, in the first chapter, he was called Elohim--a God of power but now Jehovah Elohim--a God of power and perfection, a finishing God. As we find him known by his name Jehovah when he appeared to perform what he had promised (Exodus 6:3), so now we have him known by that name, when he had perfected what he had begun. Jehovah is that great and incommunicable name of God which denotes his having his being of himself, and his giving being to all things fitly therefore is he called by that name now that heaven and earth are finished. - Matthew Henry
