Numbers 15:27-31

27Also, a person may not know that something is a sin. If he does that thing, he must sacrifice a female goat. The goat must be one year old. It will be a sin offering.

28The priest will bring the gift to the Lord. That is to make things right. Then the Lord will forgive that person who did the sin. The person did not know that he had done a wrong thing.

29The same rule is for the Israelites and for all the foreign people who live among them. That is when it was a mistake.

30But a person might do something that he knows to be wrong. He does it because he wants to do it. That person is as bad as someone who insults the Lord. It does not matter whether he is an Israelite or a foreign person. You must make that person separate from all the people.

31That person thought that the Lord's command was not important. He has not obeyed God's rules. So you must make that person completely separate from the people. He is a guilty person.’
