The tetragrammaton ,does not appear anywhere in the Christian Greek Scriptures See the New World kingdom Interlinear translation
The tetragrammaton translated in english is YHWH ( not JHVH) their is no J in hebrew.
The first edition of the book " Aid To Bible Understanding" admits that the proper pronunciation of Gods name is not known.
That they have used the name Jehovah because it is the more popular name used in Christendoms religions. And they say Christendoms religions are apostates / anti christs /Babylon The Great , can they have it both ways ?
In Isaiah43 :10 -10 Gods name is Jehovah ? Since when ? , the name jehovah never came up before the 13th century A.D.
And the JEWS AFTER THE SCRIPTURE OF ISAIAH 43:10 NEVER EVER IDENTIFIED THEMSELVES AS JEHOVAHS WITNESSES
aND FOLLOWERS OF CHRIST ARE BY" DIVINE PROVIDENCE" TO BE CALLED CHRISTIANS .
