Looking at a translation of the lords prayer, wondering where the word 'hallowed' came in, since it wouldn't have been part of the original language, I delved into why hallow was the substitute for sacred, and what the origins of 'sacred' were.
Sacere, a set-aside area, so so something set aside is 'sacred'. To hallow something is to hold it in high regard, to respect it, to put it in another category other than the normal one.
The hebrews had seven holy names and EL was one of them. Imagine if you time traveled back to that time and asked random people in the fertile crescent, who or what do you worship? They technically couldn't answer that because their beliefs told them not to say that word, but they COULD say the ____
the ____
el (blank)
the the
EL EL? I worship the ____ (cant say it, leave a blank)
A blank? Like a hollow? A word with a separate category? A set-aside-area? Sacere. Sacred. So, our father hallowed be thy name is like saying you have a separate category for that name. What is the normal category for all the normal words? You can say them and you can write them. What is special about the 'sacred' words? You don't say them.
