|Strong number||H3068 (Yĕhovah)|
In the Masoretic text, the standard Hebrew text of the Old Testament, the tetragrammaton is given as Yĕhovah. This text was vowelized in the Middle Ages. Attempting to give the original pronunciation was considered sacrilegious by this time, so this pronunciation is an artifice. Jews believe that the Lord's true name is unspeakable until the arrival of the messiah and the restoration of the Temple in Jerusalem.
The word "tetragrammaton" is from a Greek word meaning "consisting of four letters."
