"When the priests and the people which stood in the Temple Court heard the Expressed Name come forth from the mouth of the High Priest, they used to kneel and bow themselves and fall down on their faces and say, 'Blessed be the name of the glory of his kingdom for ever and ever!'"--Yoma 6:2
For many cultures throughout the world, a name is a powerful thing. It was no different for our forefathers in faith, the sons of Israel, for to them had been revealed the Holy Name of God. His Name was seen to be so powerful that only the high priest could pronounce it, and that only once a year. The Name was so great and so holy that Jews to this day do not pronounce it when reading the Scriptures, instead only saying "Adonai" (Lord). For the holiness of God is an immense flood that soaks everything relating to Him, so that from the Ark of the Covenant to the Holy Name, all is imbued with His sanctity. And this sanctity is of such a power that the one who is unprepared and unworthy is destroyed by it, as was Uzziah when he tried to touch the ark. (Just so the Eucharist is Holy, and he who partakes of it unworthily eats and drinks condemnation on himself.)
