It's a Hebrew thing. It's actually done out of reverence...
The Jews hide the Name of God, and certainly it was Satanically inspired out of some kind of false reverence, it was certainly
NOT God's desire for them to hide His
GREAT Name,
YAHWEH, for in its usage (His covenant Names) by God's People His great Love and Power is revealed and available to a needy world and Church!
Exodus 3v14-16 states: "And God said unto Moses, I AM THAT I AM: and he said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you. And God said moreover unto Moses, Thus shalt thou say unto the children of Israel,
Jehovah (YAHWEH), the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you:
this is my name forever, and this is my memorial unto all generations. Go, and gather the elders of Israel together, and say unto them,
Jehovah (YAHWEH), the God of your fathers, the God of Abraham, of Isaac, and of Jacob, hath appeared unto me, saying, I have surely visited you, and (seen) that which is done to you in Egypt:
The Jews in their false reverence removed the vowels from YAHWEH to give YHWH (The Tetragramaton).
