A Jehovah's Witness.
The personal name of God in the Hebrew Scriptures; in Hebrew, יהוה (YHVH)
Jehovah is a transliteration of the Hebrew name יהוה (YHWH), which was deliberately read with the vowels from the word "my lord" (Adonai) to avoid pronouncing the sacred tetragrammaton. This reading tradition evolved from an earlier form, Iehoua.
