Sin
The synagogue service of Yom Kippur is based on the confession of the High Priest as chronicled on chapter 16, verse 21of the Book of Leviticus. For that reason the late Israeli philosopher and biblical scholar Yehezkel Kaufmann called the Yom Kippur service “the priestly rite par excellence.”
As rabbi Adin Steinsalz, one of the most prolific and sometimes controverted Orthodox rabbis says it, “the concept of sin in and of itself is never fully developed or clarified in Judaism.”
The word “het,” one of the words used to evoke the concept of sin, is a case in point
Etymologically it refers to an act that misses the desired mark. In archery, for instance, the verb describes shooting an arrow that does not hit the target.
In other words, by using the word “het” Judaism points to a human failure.
