The name Jehovah is used some 6,800 times in the Bible. It is the personal covenant name of Israel's God. In the King James Version of the Bible, it's translated as "Lord God." Not only does it speak of God's strength, but also it speaks of the sovereignty of God and the goodness of God. The root of this name means "self-existing," one who never came into being, and one who always will be. When Moses asked God, "Who shall I tell Pharaoh has sent me?" God said, "I AM THAT I AM." Jehovah or Yahweh is the most intensely sacred name to Jewish scribes and many will not even pronounce the name. When possible, they use another name.
