YHWY {breath}

And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. Genesis 2:7

 In whose hand is the soul of every living thing, and the breath of all mankind. Job 12:10

For in him we live, and move, and have our being... Acts 17:28

“The letters of the name of God in Hebrew… are infrequently pronounced Yahweh. But in truth they are inutterable….
This word {YHWY} is the sound of breathing.
The holiest name in the world, the Name of Creator, is the sound of your own breathing. That these letters are unpronounceable is no accident. Just as it is no accident that they are also the root letters of the Hebrew verb ‘to be’… God’s name is name of Being itself.”
