What does Leviticus 4:17 mean?

He’ll take the rest of the bull outside the camp and burn it, just like with the first sin offering. This is how the priest makes things right for the community, and they’ll be forgiven. Leviticus 4:17 - Modern Text Bible

(The process ends with the removal of the leftover parts, symbolizing that the sin has been dealt with and the people are forgiven.)
