YHWH is the name of God in the Hebrew Bible, often referred to as the Tetragrammaton, which consists of four Hebrew letters: Yod, He, Waw, and He. This name is considered sacred in Judaism, and its pronunciation is traditionally avoided. Instead, Jews often use terms like Adonai or HaShem when referring to God in prayer and conversation. In Christian contexts, YHWH is often translated as "LORD" in English versions of the Bible. The name signifies God's eternal and unchanging nature, emphasizing His role as the creator and sustainer of the universe. YHWH is central to the beliefs of both Judaism and Christianity.
