English: These three occurrences of “and he shall atone” — for what do they come?
Three ve-chipper diyukim in the chapter — repeated “ve-chipper” in the nasi and individual sections teaches distinct points about kapparah.
Each occurrence of “ve-chipper” is available for a separate derivation. The Gemara uses the multiplicity to establish different rules about the nature and conditions of the atonement effected by these chatas offerings.
