What is the chapter’s core rule for whether a disqualified bird becomes nevelah?
The Rambam’s general rule: post-entry type disqualifications can make it pasul without nevelah impurity, while earlier/intrinsic defects make it nevelah.
Question 2
If melikah was done with a knife, how is the bird treated?
Melikah must be by the kohen’s thumbnail/hand procedure; knife-use removes the sacrificial melikah status and yields full nevelah treatment.
Question 3
What is the law when chattat ha-of blood is applied on the upper half of the altar?
Chattat ha-of belongs on the lower half; upper placement disqualifies whether done in chattat or olah style and regardless of intent.
Question 4
If olat ha-of was done in proper olah manner but explicitly for the sake of a sin-offering, what is the result?
Unlike chatat, an olah can remain kosher with mismatched intent, but it may fail to count for the owner’s required obligation.
Question 5
A doubtful chattat ha-of was already given melikah, then the woman is found definitely not obligated. What is done?
After melikah, if obligation is negated, the remaining rites are not performed and the bird is buried to prevent benefit.
