We believe that the pronunciation of the Sacred Name יהוה is not known today. Some ways of pronouncing it are: Yahuah, Yahweh, Yehovah, etc.
The following are various view points on how the name should be pronounced. Please study them prayerfully and ask the Set Apart Spirit to grant you discernment on how to pronounce the Sacred Name because He wants us to utter His Name and because Yahshua invoked His Name.
