TSK · Numbers 17:11

So he is to make atonement for the holy place from the impurities of the Israelites and from their transgressions with regard to all their sins, and thus he is to do for the Meeting Tent which resides with them in the midst of their impurities.

Whenever your countrymen who live in the cities bring a case before you(whether it involves a violent crime or other matters related to the law, commandments, rules, and regulations), warn them that they must not sin against the LORD. If you fail to do so, God will be angry with you and your colleagues, but if you obey, you will be free of guilt.
