Rule of R. Joshua that if the priests have once had the right to eat of a sacrifice no trespass can take place (§ 1). In this connection the question is raised whether there can be a trespass in the case of those parts of the sacrifice which have been removed from the sanctuary before the sprinkling of the blood (§§ 2-3).
The R. Joshua rule states that if priests have had permission to eat a sacrifice, no unlawful act can happen (§ 1). This is relevant when considering whether an unlawful act can occur in cases where parts of the sacrifice were taken out of the sanctuary before the blood was sprinkled (§§ 2-3).
