Altar (Judaism) in the context of "Incense offering"

A sin offering (Hebrew: קָרְבַּן חַטָּאת, korban ḥatat, IPA: [χaˈtat], lit: "purification offering") is a sacrificial offering described and commanded in the Torah (Lev. 4.1-35); it could be fine flour or a proper animal. A sin offering also occurs in 2 Chronicles 29:21 where seven bulls, seven rams, seven lambs and seven he-goats were sacrificed on the command of King Hezekiah for the kingdom, for the sanctuary, and for Judah. Like all types of sacrifices offered on the altar, the flour had to be unscented and the animal had to be completely unblemished. This offered sacrifice accompanied the important required core means of atonement for the committing of an unintentional transgression of a prohibition, that either has brought guilt upon the 'community of Israel' or the individual. This offering is brought during or after atonement for those transgressions that had been committed inadvertently, or in ignorance: intentional transgressions could only be absolved by other forms of atonement, or in severe cases kareth. It was distinct from the biblical guilt offering.
