Why YHWH?
Every translator of the Psalms must decide how to handle God’s personal name, YHWH or YHVH, which occurs repeatedly in its Hebrew text. Translators of the King James Version usually translated it “LORD” (all caps) and sometimes transliterated it (badly) as “Jehovah.” Likewise, all modern translations either translate or transliterate it. Some other options for translating it are “the Eternal,” “the Almighty,” or “the Sovereign Lord.”
While translating it aims to make it more accessible to readers, transliterating it seems to me more faithful to the text since it’s not a word at all, but rather God’s uniquely personal name. This roots it more firmly in the biblical story as the name God revealed to Moses on Mount Sinai. Meaning “the self-existent One who answers to no one,” the name YHWH set Israel’s God apart from all the gods of Israel’s neighbors.
Personal names are, well, very personal. Even the sound of a name can evoke strong emotion. I’ve chosen to transliterate only YHWH’s consonants since the earliest Hebrew manuscripts contain only consonants, the vowels being added much later. My aim in doing so is to honor God’s name and set it apart, as unique.
One problem with YHWH is that we aren’t sure how it was pronounced since Jews long ago stopped saying it out of reverence. (They read Adonai instead whenever they come to YHWH in the text.) I take the advice of my esteemed Hebrew professor, Raymond Dillard, who advocated pronouncing it as Yahveh (Yah·vay). He favored that over the standard Yahweh since the modern Hebrew pronunciation of its third consonant makes the name sound more robustly Jewish. It also makes it sound more robust, period.
