וַעֲשִׂיתֶ֕ם בְּי֥וֹם הֲנִֽיפְכֶ֖ם אֶת־הָעֹ֑מֶר כֶּ֣בֶשׂ תָּמִ֧ים בֶּן־שְׁנָת֛וֹ לְעֹלָ֖ה לַיהוָֽה׃
Vous offrirez, le jour du balancement de l’ômer, un agneau sans défaut, âgé d’un an, en holocauste à l’Éternel.
Rashi on Leviticus
ועשיתם... כבש AND YE SHALL OFFER… A LAMB — This came (was brought) as an obligatory sacrifice in connection with the Omer.
Siftei Chakhamim
An obligation in connection with the omer. Rashi is answering the question: Why in parshas Pinchas (Bamidbar 28,) which lists [all] the additional offerings [of Pesach], as Rashi explains (in verse 8), is there no mention of this sheep? He answers: This sheep is not brought as an additional offering but comes as an obligation in connection related towith the omer.
