'Inadvertent' in the Bible

Then the priest is to make atonement for the entire community of the Israelis, and they will be forgiven for inadvertent sins. They are to bring their offering, an offering made by fire to the LORD, as well as their sin offering, into the LORD's presence on account of their error.

They are to serve as cities of refuge from a blood avenger in order to keep the inadvertent killer from dying until he has stood trial in the presence of the community.

then the community is to judge between the inadvertent killer and the blood avenger, following these ordinances.

The community is to release the inadvertent killer from the blood avenger and return him to the town of refuge where he had fled. He is to live there until the High Priest dies, who will have anointed him with holy oil.

But if the inadvertent killer leaves the town of refuge where he had fled

The inadvertent killer is to live in the town of refuge until the High Priest dies. After the death of the High Priest, the inadvertent killer is to return to the land of his inheritance.
