Commentary for Leviticus 19:22

ונסלח לו מחטאתו אשר חטא AND THE SIN WHICH HE HATH SINNED SHALL BE FORGIVEN HIM — [The words מחטאתו אשר חטא appear to be redundant after the statement על חטאתו אשר חטא immediately preceding them, but they are intended] to include the willful sinner just as well as him who acts unintentionally amongst those who must bring this offering (Sifra, Kedoshim, Chapter 5 7; Keritot 9a).

[This] includes one who sinned intentionally as one who sinned unwittingly. Rashi explains in chapter Araba Mechusarei Kapara (Kerisus 9a) [where the Gemara says], “[This] includes one who sinned intentionally as one who sinned unwittingly,” that he too has to bring a sacrifice [even] for an intentional [sin in this case]. [The Gemara deduces this] because this is apparently a superfluous verse. Since it is written before “For the sin which he committed and he will be forgiven,” why does it then again write “for the sin which he committed?” This is to tell you that one brings a sacrifice even for an intentional [sin].
