Somme du gros bétail pour holocauste: douze taureaux; de plus, douze béliers, douze agneaux d’un an, outre leur oblation, et douze jeunes boucs pour expiatoire.
Ibn Ezra
The Dissenters claim that yearling does not mean “a year old” [cf. comment on 12:6]. The former, according to them, denotes an animal under one year of age, whereas the latter denotes an animal one year old or older. The passage dealing with the dedication of the Altar, however, speaks of “one yearling lamb” [Numbers 7:15], yet in the end gives a total count of “twelve one-year lambs” [Numbers 7:87].
