Is there something wrong with pronouncing G-d’s name as it is written?

One of the commandments found in the Torah is to show the greatest respect for God’s name:

Fear this glorious, awesome Name of God your Lord” (Deuteronomy 28:58)

This commandment refers specifically to the ten Hebrew names by which God is designated in the Torah. According to Jewish Law, the only time one is allowed to pronounce these names is during prayer or study, with the exception of one – the Tetragrammaton (the four-character name) – which is G-d’s highest emanation in creation. The only place where the Tetragrammaton was allowed to be pronounced as it is written was in the Temple in Jerusalem. It was pronounced by the priests in their daily blessing in the Temple, as well as ten times during the Yom Kippur service in the public confessions. There is a tradition that after Shimon the Saint died in 291 b.c.e., it’s use in the daily priestly blessing was discontinued because the Divine Presence was no longer manifest in the Temple and the regular priests felt themselves unworthy. Only the High Priest continued to pronounce it in the Yom Kippur service but in a low voice so that it would be drowned out by the singing of the other priests and no one unworthy would learn it. Some authorities maintain that it is even forbidden to simply spell out the letters of the Tetragrammaton. Therefore, when spelling out the name, we change the letter ‘Heh’ to ‘Keh’ and read Yud-Keh-Vav-Keh.As you might know, whenever the Tetragrammaton appears in a blessing or during the course of Torah study, we say ‘Adon… ’ (I’m not allowed to write it in full) one of the other names of G-d.

Sincerely,
