Positive Mitzvah 72: The Guilt-offering adjustable to financial status
-Leviticus 5:1 "And if a person sins... he shall bring his guilt
offering... but if he cannot afford..."
A person who is impure (see Positive Mitzvah 74) is forbidden to enter
the Beis HaMikdash or eat from korbonos.
Breaking an oath or taking a false oath are also forbidden.
If a person commits any of these
sins, he is commanded to bring a guilt offering.
The Torah considers his financial status. A person who cannot afford
an expensive offering is allowed to bring one which costs less.
