Yochanan (John) hears a voice that sounds like a trumpet and he is “instantly in the Spirit.” This is an allusion to the ‘blink of an eye’ at the last shofar blast, when the transformation from flesh bodies to spirit bodies takes place in a ‘moment’ at the first resurrection. The Hebrew word for ‘moment’ is rega and means ‘just a moment, wait.’ The prophet Isaiah reveals more about the ‘blink of an eye.’
For centuries the ‘Yod Hey Vav Hey’ has been considered too holy to speak, consequently, the actual pronunciation of God’s memorial name has been lost. It was replaced in Jewish tradition with HaShem meaning ‘The Name’ or Adonai meaning ‘Lord.’ In more Orthodox communities, the words ‘God’ and ‘Lord’ have their vowels removed and become G-d and L-rd to show respect for God’s name. Because of these historical and cultural anomalies, the Preface in most Bibles says that the divine name for God or Tetragrammaton has been changed from the יהוה to LORD with all capitals letters.
