Shavua Tov. During these final days of עשרת ימי תשובה, we are to focus on different aspects of coming closer to Hashem and repenting. There is a pretty well known statement of the Rabbis that teaches us that Hashem is able to tolerate when one sins against man and G-d, but He cannot tolerate when people sin against one another. An example of this was the reason for the "flood". Despite the horrible sins that generation was committing, it was stealing, a sin between man and man, that sealed their fate. For this reason, Yom Kippur only atones for sins between man and G-d, and does not atone for sins between man and man. Therefore, between now and Yom Kippur, we are to sincerely ask for forgiveness from anyone we may have wronged, so that we can enter Yom Kippur with a clean slate.
