Halakha Bilangan 28:19: Sefer HaChinukh & Shulchan Arukh, Orach Chayim

וְהִקְרַבְתֶּ֨ם אִשֶּׁ֤ה עֹלָה֙ לַֽיהוָ֔ה פָּרִ֧ים בְּנֵי־בָקָ֛ר שְׁנַ֖יִם וְאַ֣יִל אֶחָ֑ד וְשִׁבְעָ֤ה כְבָשִׂים֙ בְּנֵ֣י שָׁנָ֔ה תְּמִימִ֖ם יִהְי֥וּ לָכֶֽם׃

Kamu harus mempersembahkan kurban api, kurban bakaran bagi Yang Mahakekal: dua ekor lembu jantan muda, seekor domba jantan dewasa, dan tujuh ekor domba jantan berumur satu tahun; semuanya haruslah tidak bercacat bagimu.

Sefer HaChinukh

The commandment of the additional sacrifices all of the seven days of Pesach: To sacrifice the additional sacrifice on all of the seven days of Pesach, as it is stated (Leviticus 23:8), “And you shall offer a fire-offering to the Lord seven days.” And it is like the sacrifice of Rosh Chodesh (the new moon): two bulls; one ram; seven sheep — all of them burnt-offerings, and as it is written explicitly about all of them in the Order of Pinchas (Numbers 28:19), “a fire-offering, a burnt-offering,” and I have already explained the statute of a burnt-offering above (Sefer HaChinukh 115) — [and one goat as a sin-offering, and it is eaten].
