Hebrew: יהוה and its transliteration “YHWH”
Variations: YHVH, JHVH, JHWH, Yehowah, Yahweh, Yahwe, Yahveh, Yahve, Wahvey, Jahvey, Jahweh
the special and significant name (not merely an appellative title such as Lord [Adonai]) by which God revealed himself to the ancient Hebrews (Exodus 6:2-3) / transliterated from the Hebrew consonants יהוה (Hebrew is written right-to-left)…
This name, the Tetragrammaton of the Greeks, was held by the later Jews to be so sacred that it was never pronounced, except by the high priest on the great Day of Atonement, when he entered into the most holy place.
Whenever this name occurred in the sacred books, they pronounced it, as they still do, “Adonai” (i.e., Lord), thus using another word in its stead (Hebrew: אֲדֹנָי). The Massorets gave to it the vowel-points appropriate to this word (יְהֹוָה).
The Hebrew name “YHWH” (Jehovah) is generally translated in the King James Version (and the Revised King James Version did not departed from this rule) by the word “LORD” printed in small capitals, to distinguish it from the rendering of the Hebrew Adonai and the Greek Kyrios, which are also translated Lord, but printed in the usual type.
