הלכה על זבחים 5:5

And the Torah further also obligated this sacrifice for one who has sexual relations with a designated maidservant; and as it is written in the Order of Kedoshim Tehiyu, as it is stated (Leviticus 19:20-21), "If a man lays with a woman, etc. and she is a maidservant designated (charufah) for a man, but has not been redeemed with redemption, etc. there shall be an investigation, etc. And he shall bring his guilt-offering[, etc.] a ram of guilt." And this is from those that come whether for inadvertent transgression or volitional (Keritot 9a). It comes out that with all of them, there are five definite guilt-offerings. And so did the Sages, may their memory be blessed, count in the Mishnah, such that they said (Mishnah Zevachim 5:5), "These are the guilt-offerings: 1) The guilt-offering of thefts; 2) the guilt-offering of misappropriations; 3) the guilt-offering of the designated maidservant; 4) the guilt-offering of the nazirite; 5) the guilt offering of the metsora." And [regarding] the undetermined guilt-offering which is counted there, its name is upon it [to show] that it is not from the group of definite guilt-offerings. And from these five, three of them come whether they are inadvertent or volitional - and they are the guilt-offering of thefts, the guilt-offering of the designated maidservant and the guilt-offering of the nazirite; and one of them only comes for inadvertent transgression and not for volitional transgression - and that is the guilt-offering of misappropriations; and [for] the fifth - which is the guilt offering of the metsora - the expression, inadvertent and volitional, is not relevant, as we said.
