Jehovah

The term "Jehovah" is a Medieval attempt to approximate the divine Hebrew name (YHWH). It is not more literal, respectful, or accurate than other typical attempts to represent the original term. The personal name of God in the Hebrew Bible is יהוה (YHWH), which occurs over 6,800 times in the Old Testament. The term "Jehovah" is a Medieval mistranscription from the Masoretic Hebrew Bible, combining the consonants of the divine name YHWH with the vowels of another Hebrew word, 'adōnāy (“my lord”).

The pronunciation of "YHWH" was not determined in ancient Hebrew, and the "J" sound was not present. The "W" in "YHWH" is rendered from the "V" in "Jehovah," as the Hebrew letter vav. The Masoretes, Jewish scribes in the Middle Ages, were responsible for applying vowel symbols to the consonantal text to preserve the precise pronunciation of the text. [GotQuestions]

The term "Jehovah" is less than 700 years old and became increasingly used in early English translations. It is used in the King James Version of the Bible and is also promoted by Jehovah’s Witnesses. However, most scholars do not believe "Jehovah" to be the proper pronunciation of YHWH, and the name "Yahweh" or "Yehowah" is more likely to be the correct pronunciation. [The Gospel Coalition]
