YHWH - the divine name for the God of Israel given in Exod. 3:14. When Moses asked God to reveal His name so that he could tell the Israelites in Egypt who had sent him, God said that His name was "I AM WHO I AM." While that phrase did provide a name to call God, the name was still very mysterious since it could be translated in various ways (e.g., "I AM WHO I WILL BE," "I WILL BE WHO I AM," "I WILL CREATE WHAT I CREATE") and since one could never know God in all His fullness. Israel could not refer to God as "I AM" so they called him YHWH "He is." As time passed by the name was considered too holy to even pronounce so it has come down to us with no vowels. Most suspect the name with vowels was "Yahweh" but no one is certain. In the Masoretic text, the name was written with the vowels from 'adonai, the name for "lord" to ensure that when a reader came to the divine name he would say the word "lord" rather than pronounce the divine name. Mistakenly assuming that the vowels that appear with YHWH are correct, the name "Jehovah" was created. "Jehovah" is a hybrid name composed of the consonants of YHWH and the vowels of 'adonai. Some modern translations like the New Revised Standard Version indicate the translation of the divine name by writing LORD in all capital letters.
