וכבשה אחת AND ONE EWE-LAMB for a sin-offering.

AND ON THE EIGHTH DAY HE SHALL TAKE TWO HE-LAMBS WITHOUT BLEMISH, AND ONE EWE-LAMB. Scripture has not explained what is to be done with the two he-lambs and the one ewe-lamb. However, it mentioned concerning one of the he-lambs that the priest offer it as a guilt-offering,⁶⁸Verse 12. and further mentioned that he should offer up the sin-offering,⁶⁹Verse 19. and afterward he shall slaughter the burnt-offering.⁶⁹Verse 19. This is because He has already mentioned in the section of Vayikra that the sin-offering should be a female,⁷⁰Above 4:28; 32. and that every burnt-offering should be a male.⁷¹Ibid., 1:3; 10. Therefore there was no need here to speak at length, it being known that [since the first he-lamb was a guilt-offering], the second he-lamb would be the burnt-offering, and the ewe-lamb would be the sin-offering.

יקח שני כבשים תמימים וכבשה אחת, “he is to take two unblemished sheep and one ewe;” Nachmanides points out that the Torah did not state what is to be done with these three animals except to say that one of the male sheep mentioned is to serve as a guilt-offering, the priest having heaved it before Hashem. In verse 19 the Torah does state that the metzura is to offer his sin offering and his burnt offering, without referring to a specific animal. Seeing that we had learned in Parshat Vayikra that every sin offering, if consisting of the species sheep, consists of a feminine species, it is clear that the ewe is to serve as the sin-offering and the remaining male sheep as the burnt offering.
