During the OT times the religious of the day came to a conclusion. That if the Almighty was Holy and His Name was Holy then because no man could live if he laid eyes on the Almighty. Then they had better not say His Name nor write His Name. There was one allowance and that was once a year. The Name was to be muttered by the priest in the Holy of Holies, but so quietly that no ear should hear His Name and perish.
Why? Because it pleased Yah Veh Elohim to hide from this people the only Name that could save them. If they couldn’t cry out to Him then He didn’t need to save them.
He has hidden His Name again. He moved the translators to change all the Names and Titles He had revealed. Judgment declares that that those who shall be saved will be given the Name to call upon for salvation.
