פירוש על ויקרא 5:18

‎ לאשם בערכך [HE SHALL BRING A RAM …] ACCORDING TO THE VALUATION FOR A GUILT OFFERING — i. e. according to the value stated above (v. 15, viz., at least 2 shekels).

This is why the Torah adds the rider על שגגתו אשר שגג והוא לא ידע, seeing that every שוגג, inadvertently committed sin, contains an element of being unaware of it, why would the Torah have to add the words “and he did not know?” [Had he known, the sin would have been deliberate and no sacrifice would exonerate him. Ed.] The error consisted of mistakenly eating something not kasher instead of picking up the similar looking kasher item next to it. At the time the person thought that both were kasher so that there was nod doubt in his mind. By the time he found out, the other piece had disappeared. If for some reason he becomes aware later that he had indeed eaten the forbidden piece of meat he will have to bring an additional sin-offering. The effect of the asham taluy protected him only until clarification of the true state of affairs.

In the value recorded. It is the value of two silver selaim (shekalim) of holy selaim. You might ask: Say that the guilt-offering of the nazir and the guilt-offering of the metzoro is two selaim, and the guilt-offering [brought by one who seduced] an engaged maidservant is even one sela. The Sages answered this question in Toras Kohanim: I include the guilt-offering of an engaged maidservant which is a [two-year old] ram, the same as the uncertain guilt-offering, and I exclude the guilt-offering of the nazir and metzoro which is a [one-year old] lamb and not a ram.
