Bilangan 8:21

8:21 The Levites purified themselves ¹  and washed their clothing; then Aaron presented them like a wave offering before the Lord, and Aaron made atonement for them to purify them.

Bilangan 15:23-24

15:23 all that the Lord has commanded you by the authority ²  of Moses, from the day that the Lord commanded Moses and continuing through your future generations – 15:24 then if anything is done unintentionally ³  without the knowledge of ⁴  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.

[8:21]  ¹ tn The verb is the Hitpael of חָטָּא (khatta’). In this stem the meaning of the root “to sin” is likely to be connected to the noun “sin/purification” offering in a denominative sense, although some would take it as a privative usage, “to remove sin.” The idea is clear enough: They performed all the ritual in order to purify themselves ceremonially.

[15:23]  ² tn Heb “hand.”

[15:24]  ³ 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]  ⁴ tn Heb “[away] from the eyes of the community.”
