Rashi on Deuteronomy 17:1/רש"י על דברים י״ז:א׳

1לא תזבח ... כל דבר רע THOU SHALT NOT SACRIFICE [UNTO THE LORD THY GOD ANY OF THE HERD OR FLOCK WHEREIN IS BLEMISH OR] ANY EVIL THING — This is an admonition to one who would make sacrifices abominable through an evil utterance (דבר רע). (See Rashi on Leviticus 7:18; cf. Sifrei Devarim 147:5). Besides this, other Halachas have been derived from it in the Treatise on “The slaughtering of Sacrifices” (Zevachim 36).
