I have been practicing Hebrew Calligraphy.
This tetragrammaton, יהוה YHVH, is the most sacred name of God. It’s derived from the root הוה meaning: Was, Is, Will Be, referring to the eternal being of God. As it is said: “And they shall know that you are your name, YHVH; You alone are supreme over the whole land.”–Psalms 3:19
Jews are forbidden to pronounce the name out of reverence and to avoid taking God’s name in vain; only the high priests at the time of the temples were allowed to speak it. We read this name as Adonai (My Lord), or Hashem, (The Name), and typically replace it with ‘ה. “Thou shalt not bear the name of the LORD thy God in vain(Exodus 20: 7).
יהוה is the most common name of God in the Bible. It is used 6,823 times and found in all but three books of the Old Testament (Ecclesiastes, Esther, and Song of Songs). יהוה is Typically combined with other words to show us His character even more specifically, for example: יהוה אֱלֹהִים Lord God, יהוה אֵל עֶלְיֹון Lord God Most High.
Since it has no vowels, the usual transliterations, Jehovah or Yahweh, are inaccurate renditions based on a misunderstanding of the way it is printed.
