Actually, God’s name in the original Hebrew Scriptures – without the vowel points - was written out as, “YHWH”. Over the course of time they fell out of the custom of using Yahweh because it was treated as very sacred. They needed something else to call him and substituted Yahweh with Ado-nai, which means, “my lord”. Later, to remind the reader to say Ado-nai instead of Yahweh, they added the vowel points for Ado-nai around the original, YHWH and that’s where you get the name HEHOVA if you pronounce “J” the English way, instead of the German way, which sounds like a “Y”.
The first person to treat the letters with the vowel points as the name, “Jehovah”, instead of simply a memory cue (as the Hebrews intended), was C.E. Raymundus Martini, a Spanish monk of the Dominican Order, used it in his book *Pugeo Fidei *of the year 1270. Hebrew scholars generally favor “Yahweh” as the most likely pronunciation.
