Numbers 7:87-88

7:87 All the animals for the burnt offering were 12 young bulls, 12 rams, 12 male lambs in their first year, with their grain offering, and 12 male goats for a purification offering. 7:88 All the animals for the sacrifice for the peace offering were 24 young bulls, 60 rams, 60 male goats, and 60 lambs in their first year. These were the dedication offerings for the altar after it was anointed. 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.

Numbers 29:13

29:13 You must offer a burnt offering, an offering made by fire as a pleasing aroma to the Lord: thirteen young bulls, two rams, and fourteen lambs each one year old, all of them without blemish.

[7:88]  ¹ sn Even though the chapter seems wearisome and repetitious to the modern reader, it is a significant document. A. Rainey shows how it matches the exact ledgers of ancient sanctuaries (see ZPEB 5:202). The recording would have been done by the priestly scribes. Of the many points that can be observed here, it should not be missed that each tribe, regardless of its size or relative importance, was on equal footing before the Lord. Each tribe shared in the work of the Lord equally. Each tribe approached the sanctuary in precisely the same way on this memorable occasion. All such devotion to the work of the Lord was to receive the blessing of God.

[15:24]  ¹ 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]  ² tn Heb “[away] from the eyes of the community.”
