In regards to JEHOVAH, a remarkable thing about the King James Bible is that the name is found exactly 7 times - Genesis ; Exodus 6:3, ; Judges ; Psalm ; Isaiah 12:2 and 26:4. This Hebrew word (There are actually two variants of this Hebrew word; one is # 3068 Jehovah and the variant #3068 Jehovih.) is translated three different ways by the KJB. The NASB only translates this word in two ways--as LORD, and GOD.The NKJV has either LORD, GOD or inconsistently as YAH.
God is the creator, Lord is the sovereign ruler of His creation, and JEHOVAH is the personal name of the Redeemer God, who redeems His people.
The first time JEHOVAH appears is in Genesis when Abraham is stopped from offering up his son Isaac.
All of this of course is a type of the Father offering up His Son.
"And Abraham called the name of the place JEHOVAH-jireh: as it is said to this day, In the mount of the LORD it shall be seen".
The second time the name appears (and Christ is the second person of the trinity) is in the second book of Exodus, which is the book of redemption.
