This is partly because God has many names in Scripture. Each serves as an important key in disclosing His doctrine, character, power, holiness, and desired relationship with His people. This name is frequently used to support the truth of the trinity. Jesus also has many names in the Scriptures. On our weekly Bible Answers Live radio program, an increasing number of people are calling with a burden regarding the correct pronunciation of God's name.
Nobody seems exactly sure how to pronounce that word.
It is a combination of four Hebrew consonants, YHWH, which is known as the Tetragrammaton. In time it was thought that the divine name was too holy to pronounce at all. Many translations of the Bible followed this practice. Over the course of centuries, the correct pronunciation of YHWH was lost. Jewish scholars in the Middle Ages developed a system of symbols placed beneath and beside the consonants to indicate the missing vowels.
