Nazir 27: Sons and Fathers

R. Nachman's position on a designated animal that ends up being blemished - already consecrated for the nazir's offerings. Is it to be treated like an unallocated animal or an allocated one? R. Hamnuna questions whether the blemished animal could be treated like unspecified funds. Plus, Rava's objection to R. Nachman - via a son and father needing to bring their own respective sin-offerings, as per a verse.
