What is God's name? Is it "God", "Lord", or something else?

'Jehovah' is a rendering of God's name that has been recognized for centuries. In the original Hebrew text, the name appears nearly 7,000 times. Its use throughout the Scriptures far outnumbers that of any of the titles, such as "Sovereign Lord" or "God," applied to Him.

Here are the four instances the name "Jehovah" is used in the King James Bible:

In Hebrew, God's name appears as four consonants. These consonants are transliterated YHWH and are known as the Tetragrammaton.

At some point a superstitious idea arose among the Jews that it was wrong even to pronounce the divine name. Evidently, later copyists kept to following the tradition of eliminating the distinctive name of God by replacing it with Ky´ri·os and The·os´ ("LORD" and "GOD"). Unfortunately, because of the superstitions and traditions (things which Jesus condemned -Mt. 15:1-9) concerning the Divine Name, God's name was generally removed from the texts altogether.

However, Jesus even noted that God's name is to be regarded as Holy (or "Hallowed") and this surely wouldn't mean for it to be withheld from usage or omitted from His Word the Bible. (Mt. 6:9)
