The word "Jehovah" is included seven times in the King James Bible. "Jehovah" appears in the books of Genesis, Judges and Psalms once, while it appears twice each in Isaiah and Exodus.
Throughout the various versions of the Bible, the word "Jehovah" is swapped for "The Lord" or "Yahweh," depending on the area of the world where that particular version was translated and printed. Various Christian and Jewish sects take different stances on what word should be used to portray the name of God. Despite these differences, the various sects tend to have near-complete agreement on other facets of God.
