“That which is for the chatas first” — this becomes a binyan av (prototype rule) for all chatas offerings: whenever a chatas and an olah are brought together, the chatas is offered first.
Type of Learning: Binyan av drawn from the explicit priority language “la-chatas rishonah”: the order stated here is the model for every paired chatas-and-olah service.
What Is Learned: Whenever the Torah or the court requires both a chatas and an olah in one procedure, the chatas is performed before the olah. The sequence is not optional; it is fixed by this verse’s prototype.
