The tetragrammaton in Phoenician (12th century BCE to 150 BCE), Paleo-Hebrew (10th century BCE to 135 CE), and square Hebrew (3rd century BCE to present) scripts
The tetragrammaton (n/; from GreekΤετραγράμματον, meaning "[consisting of] four letters"), יהוה in Hebrew and YHWH in Latin script, is the four-letter biblical name of the God of Israel. The books of the Torah and the rest of the Hebrew Bible (with the exception of Esther and Song of Songs) contain this Hebrew name. Religiously observant Jews and those who follow Talmudic Jewish traditions do not pronounce יהוה, nor do they read aloud transliterated forms such as Yahweh; instead the word is substituted with a different term, whether used to address or to refer to the God of Israel. Common substitutions for Hebrew forms are hakadosh baruch hu ("The Holy One, Blessed Be He"), Adonai or HaShem ("The Name").
