Wikipedia notes that
Because of its unsurpassed holiness, from postexilic times pious Hebrews declined to pronounce the name in reading, and only the consonants YHWH were written. The vowels we see today were later added by religious scribes.
The precise meaning of the Hebrew name Yahwey is debated. Some say it builds on the Hebrew word haya meaning “be, become” or “cause to be.”
In a Masoretic Text a vowel is included, bringing the word closer to donay and suggesting the meaning “Lord.”
In the story of the Burning Bush (Exodus 3:14) God reveals himself to Moses, saying his name is “I Am who I Am.” And many other names and titles are used for God throughout the OT, such as “Ancient of Days” (Daniel 7:13), “Father” (Jerimiah 3:19) “Maker” (Isaiah 17:7) and “Lord of hosts” (Amos 4:13).
a god Yahweh may have been worshiped south of the Dead Sea at least three centuries before the emergence of Israel (the Kenite hypothesis).†
To me, it seems superficial to get hung up on what to call God, and far more important to try to figure out what God wants us to do.
