Rashi comments on שמות כא,ו, quoting the מכילתא and קידושין דף כב עמוד ב, that an עבד עברי who was sold into slavery due to stealing has a hole put in his ear for not listening to לא תגנוב and one in slavery due to selling himself must experience the same as he didn't listen to כי לי בני ישראל עבדים. Two questions:
- Why do you get this punishment for specifically these עבירות? This logic would seem to apply to all עבירות!
- Why do you only get this when choosing to stay after six years of slavery? You did this עבירה at the beginning of the six years!
I'm sure these questions are really famous...
