I might think that if one sacrificed (contrary to the prescribed order) a burnt-offering before a sin-offering, a Pesach offering before a daily offering (tamid), additional offerings (mussafim) before daily offerings, he transgresses a negative commandment; it is, therefore, written "You shall not sacrifice to the L-rd your G-d an ox or a sheep in which there is a blemish." For this he transgresses a negative commandment and not for the others.

"in which there is a blemish": This tells me only of a blemish. Whence do I derive (the same for) one that is scrofulous, warty, or scabbied? From "any unseemly thing."
