Nature of the Chatat

Exegetical Approaches

This topic has not yet undergone editorial review

Sin Offering

The Chatat serves to atone for sins.

Meaning of Chatat – Many verses in Tanakh1 suggest that the word "חַטָּאת" means "sin". The offering is so called as it serves to atone for sin. Ramban adds that the word takes the specific connotation of "miss the mark," pointing to Shofetim 20:16, "קֹלֵעַ בָּאֶבֶן אֶל הַשַּׂעֲרָה וְלֹא יַחֲטִא" as evidence of this usage. As such, it refers to inadvertent sins rather than intentional ones.
Who must bring a Chatat: common denominator
    • Sin – These sources might suggest that all cases in which a Chatat is brought involve sin of some sort.  Vayikra 4 speaks explicitly of those who inadvertently transgress a sin.2 The birthing mother, metzora, and Nazirite are similarly obligated for they, too, are understood to have sinned, despite the sin not being explicit in Torah.3
    • Change of status – Alternatively, one might suggest that the unifying factor between all those who bring a Chatat is that the individual is undergoing a change in status. The inadvertent transgressor transitions from sinner to innocent, from someone who deserved to be cut off, to someone who is welcomed back into the community.  The physically impure similarly transition from impure to pure and from being distanced from the Mikdash to being close. The Nazirite, too, moves from a place of separation back into society.4
How does the Chatat serve to atone?
  • Replacement for the sinner – Ibn Ezra and Ramban suggest that the sacrifice serves as a substitute or redemption (כופר נפש) for the sinner, as it is killed in the individual's stead.5 Moreover, in watching the animal slaughtered, the person is forced to recognize that it should have been his blood which was spilled had it not been for Hashem's mercy.6 This knowledge should prevent him from sinning further.
  • Enable repentance and change – Others suggest that in reality it is the individual's personal repentance rather than the sacrifice which expiates for sin.  The sacrificial process is necessary only to lead the sinner to this repentance and enable a fresh start.
    • Sefer HaChinukh asserts that the process of having to actively bring an offering (rather than simply confessing by mouth) leads one to recognize the gravity of his sin and regret and repent of his actions ("אחרי הפעולות נמשכות לבבות").7
    • R. Yosef Bekhor Shor and Ralbag add that if there was no way of cleansing one's self from sin, people would be less likely to be wary of future sins, thinking that they would remain stained regardless. The sacrificial process was instituted so that individuals can feel that their slate has been wiped clean, thereby providing an incentive to subsequently remain pure.8
"וְכִפֶּר עָלָיו" – The root "כפר" can be defined in various manners, each corresponding to this position's understanding of the Chatat's purpose:
  • Rashi and Ralbag asserts that "כפר" means to wipe away or remove.9 This suggests that the sacrificial procedure serves to wipe away the need for punishment or, perhaps, the sin itself.10 Shadal, pointing to Bereshit 6:14, "וְכָפַרְתָּ אֹתָהּ מִבַּיִת וּמִחוּץ בַּכֹּפֶר" similarly suggests that the word means to "cover". Via the offering, one's sin is covered, as if it has disappeared.
  • Ibn Ezra and Ramban, in contrast, suggests that the root "כפר" relates to the phrase "כֹּפֶר נַפְשׁוֹ", meaning ransom.  The Chatat acts as a redemption for the sinner, being offered in his place.
Role of blood – Ramban asserts that the animal's blood is supposed to represent and substitute for the sinner's soul, being sprinkled on the altar in his stead. The unique language of "נתינת דם" (rather than זריקת דם) might imply that blood plays a more important role in this sacrifice than others, due its role in the atonement process.
Status related – Chatatot and their protocols are divided based on the status of the person who sinned (with those of higher stature bringing more expensive animals and their blood being sprinkled deeper in the Mishkan's precincts) because the more important the person the more serious his transgression is deemed.11
Role of סמיכה – These sources present two understandings of this procedure:
  • Transfer of sin – Ralbag12 asserts that the laying of hands is a symbolic act, representing the transfer of sin from the transgressor to the animal.13  This is meant to allow the sinner to feel that his sins were in fact removed and that he is now clean.14
  • Appointing of substitute – R. D"Z Hoffmann notes that throughout Torah, "סמיכה" represents the choosing of another as a substitute.15 If so, perhaps here the point is to signify that the animal is taking the place of the human, being punished in his stead.
Burning outside the camp – Rambam asserts that the flesh of the offerings of the Priest and Community are burned outside the camp because they carry grave sins, and are thus too contaminated to be brought on the altar of the Mishkan.16  For the same reason, the smoke of these offerings are not described as a "לְרֵיחַ נִיחֹחַ לַי״י". In contrast to a burnt offering (עולה) whose fragrance is pleasing, the smoke of these sin offerings, representing the guilt of the nation, is offensive.17
Not called an "אִשֶּׁה לַי״י"
"וְנִסְלַח לוֹ" – As this position maintains that forgiveness is the end goal of the whole procedure, it is expected that after describing th various protocols the verse should state, "וְנִסְלַח לוֹ".
Gradated offerings (עולה ויורד) – According to these sources the gradated offerings of Vayikra 5 function like a regular Chatat, also serving to atone for sin.  According to R"Y Bekhor Shor18 and Ramban,19 is only because the sins are less severe that one is offered the possibility of giving a less expensive offering.  Sefer HaChinkuh, in contrast, suggests that the leniency stems from the factt hat these specific sins are very common and easily transgressed.20
Comparison to Asham

Purification Offering

The Chatat is primarily a purification offering.

Meaning of Chatat – According to these sources,22 the root "חטא" means to purify, as proven by the many verses where it is clearly mentioned in the context of purification (sometimes being parallel to the root "טהר") including Vayikra 14:48-52, Bemidbar 8:7Bemidbar 19:19 and Yechezkel 43:23-26.23
Who must bring a Chatat: common denominator – R. D"Z Hoffmann asserts that the common denominator between all cases in which one must bring a Chatat is that they involve contraction of impurity, be it spiritual or physical. Thus, both those individuals who have obtained and imparted spiritual impurity by unintentionally transgressing a prohibition and those who have contracted physical impurity (a birthing mother, one who has tzara'at, one who has an emission, and a Nazirite who has come in contact with a corpse) are obligated to bring a Chatat.24
What does the Chatat purify? R. Hoffmann explains that sin defiles25 not just the person, but also the Mikdash,26 and as such, the Chatat comes to purify also the Mikdash itself from impurity. As evidence that the Mikdash itself can be polluted not just via physical impurity but by sin as well, he points to Vayikra 16:16, "וְכִפֶּר עַל הַקֹּדֶשׁ מִטֻּמְאֹת בְּנֵי יִשְׂרָאֵל וּמִפִּשְׁעֵיהֶם לְכׇל חַטֹּאתָם" and Vayikra 20:3, "כִּי מִזַּרְעוֹ נָתַן לַמֹּלֶךְ לְמַעַן טַמֵּא אֶת מִקְדָּשִׁי".
Where is the Chatat blood sprinkled? In support of the assumption that the Chatat is meant to purify the Mikdash itself, R. Hoffmann notes that the blood of such offerings is sprinkled not on the person but in the Mikdash. He further suggests that the gravity of the sin determines the depths to which the Mikdash is polluted, and hence, where exactly the blood is sprinkled:
  • Unintentional sins of an individual are the least defiling and affect only the courtyard. As such, the blood of these Chatatot is sprinkled on the outer altar.
  • Inadvertent sins of the high priest (Vayikra 4:1-12) and community (Vayikra 4:13-21) affect even the Outer Sanctum and thus, the blood of their Chatatot is sprinkled on the Incense Altar.
  • Brazen sins penetrate to even the Inner Sanctum, and this is purified through the blood of the Yom HaKippurim offerings, sprinkled in the Holy of Holies. [For further discussion on the role of the various Chatatot of Yom HaKippurim see Purpose of the Service of Vayikra 16.]
Role of the blood: "וְנָתַן... מִן הַדָּם" – According to this approach, the sprinkling, placing, and pouring of the blood is the focal point of the sacrificial protocol as it is the blood which serves as the purifying agent.  This might be supported by the unique language of "נתינת דם" which is found only by the Chatat (rather than "זריקת דם" found by other offerings). This language implies that the blood of the Chatat is not merely thrown, but actively placed on the defiled areas.27
Status related – In contrast to other offerings, Chatatot and their protocols are divided based on the status of the person who sinned. As mentioned above, this is due to the fact that the higher the status, the more defiling the sin, and hence both the bigger the offering required and the deeper into the Mikdash that the blood must be sprinkled.
Not called an "אִשֶּׁה לַי״י" – R. D"Z Hoffmann suggests that while other sacrifices are referred to as an "אִשֶּׁה לַי״י", by the Chatat this is not emphasized because the focal point of the sacrifice is not its consumption by fire, but its purifying of the altar.
Role of סמיכה – This position might suggest that the "hand leaning" has no symbolic value and is not integral to the purification process (and, as such, is not unique to this offering).  It might  simply demonstrate ownership of the animal being sacrificed.
For which transgressions? This approach might suggest that any unintentional transgression, even if not overly severe, would require an offering, for all transgressions contaminate the Mikdash.28
"וְכִפֶּר עָלָיו" – This approach might suggest that he root "כפר" refers to the purging of defilement rather than atonement. See, for example, Vayikra 12:7-8, Vayikra 14:18-20Yechezkel 43:26 and Yechezkel 45:18-20 where the root is paired with the root "טהר".‎29
"וְנִסְלַח לוֹ" – This phrase is somewhat difficult for this position, which suggests that the sacrifice is not meant to atone, but only to purify.  One might respond that with purification comes forgiveness.30
Gradated offerings (קרבן עולה ויורד) – This position31 might suggest that in certain cases of impurity, where there is no active transgression but rather the omission of an act, the Torah is lenient, allowing one's economic means to determine what is brought as the offering.32 
  • Delayed purification – Vayikra 5:2-4 is understood to refer to a case in which someone contracted impurity by touching a defiled object or corpse and then forgot to purify one's self (even if one does not subsequently enter the Mikdash or eat of consecrated food). Since postponing one's purification might cause a build-up of impurity which can then contaminate the Mikdash, a Chatat is necessary.  However, since the actual defilement is not prohibited33 and the delay in purification was an unintentional crime of omission, there is room for leniency.
  • Abrogation of oaths – Vayikra 5:1 refers to case where one does not bear testimony despite hearing an oath/curse requiring it.34  As such it is similar to a case in which one accidentally does not fulfill a vow (Vayikra 5:4) in that both relate to oaths but are crimes of omission rather than active performance of a prohibited action. This position might suggest that abrogation of oaths normally causes Temple impurity, requiring a Chatat, but since these cases do not involve any action (but the lack thereof), the Torah allows for a lower grade of offering.
Difference from Asham – R. Hoffmann suggests that though both the Chatat and Asham are obligatory sacrifices, offered in the wake of sin, they serve different functions.  While the Chatat is mainly a purification offering, the Asham is primarily a reparations offering, meant to compensate for benefiting from the Sancta.
