The KJV was not based on Ethiopic manuscripts, but on Byzantine ones.

Please stop using Yahweh bless. It is offensive. For someone who claims to believe the KJV, you are correcting part of it. Yahweh came from higher critics who do not believe in the preserved Hebrew Masoretic text - and their critical texts do not have vowels, therefore they supplied their own, and came up with Yahweh - less than 200 years ago. It is not a name found in the Bible or in the preserved texts.

How do I know Jehovah is correct? Read your KJV. Names like Jehoshua, Jehoshaphat, Jehoakim, etc. all contain the same first part - yet we see them as "Jeh...", not as Yahoshua, Yahoshaphat, Yahoakim, etc.
