Whats the difference between Jehovah and Yahweh

Je‧ho′vah) [the causative form, the imperfect state, of the Heb. verb ha‧wah′ (become); meaning “He Causes to Become”].

The personal name of God. (Isa 42:8; 54:5) Though Scripturally designated by such descriptive titles as “God,” “Sovereign Lord,” “Creator,” “Father,” “the Almighty,” and “the Most High,” his personality and attributes—who and what he is—are fully summed up and expressed only in this personal name.—Ps 83:18.

Correct Pronunciation of the Divine Name. “Jehovah” is the best known English pronunciation of the divine name, although “Yahweh” is favored by most Hebrew scholars. The oldest Hebrew manuscripts present the name in the form of four consonants, commonly called the Tetragrammaton (from Greek te‧tra-, meaning “four,” and gram′ma, “letter”). These four letters (written from right to left) are הוהי and may be transliterated into English as YHWH (or, JHVH).

The Hebrew consonants of the name are therefore known. The question is, Which vowels are to be combined with those consonants? Vowel points did not come into use in Hebrew until the second half of the first millennium C.E. Furthermore, because of a religious superstition that had begun centuries earlier, the vowel pointing found in Hebrew manuscripts does not provide the key for determining which vowels should appear in the divine name.
