Bamidbar 28:17-19

Orthodox Jewish Bible

¹⁷ And in the fifteenth day of this month is a Chag (i.e., Chag HaMatzot): shivat yamim shall matzot be eaten.

¹⁸ In the yom harishon shall be a mikra kodesh (holy convocation); ye shall do no manner of melekhet avodah therein;

¹⁹ But ye shall offer a fireoffering for an olah unto Hashem; two young bulls, and one ram, and shivah kevasim of the first year; they shall be unto you temimim (unblemished ones).
