Numbers 8:8

8:8 Then they are to take a young bull with its grain offering of fine flour mixed with olive oil; and you are to take a second young bull for a purification offering. ¹ 

Numbers 15:24

15:24 then if anything is done unintentionally ²  without the knowledge of ³  the community, the whole community must prepare one young bull for a burnt offering – for a pleasing aroma to the Lord – along with its grain offering and its customary drink offering, and one male goat for a purification offering.

[8:8]  ¹ sn The first sacrifice was for the purification of the Levites. The second animal, which Moses was to take, would be used for the purification of the tabernacle from all pollution.

[15:24]  ² tn The idea of לִשְׁגָגָה (lishgagah) seems to be that of “inadvertence” or “without intent.” The text gives no indication of how this offense might be committed, or what it might include. It probably describes any transgressions done in ignorance of the Law that involved a violation of tabernacle procedure or priestly protocol or social misdemeanor. Even though it was done unintentionally, it was still a violation and called for ritual purification.

[15:24]  ³ tn Heb “[away] from the eyes of the community.”
