Numbers 15:25

15:25 And the priest is to make atonement for the whole community of the Israelites, and they will be forgiven, because it was unintentional and they have brought their offering, an offering made by fire to the Lord, and their purification offering before the Lord, for their unintentional offense.

Numbers 16:46

16:46 Then Moses said to Aaron, “Take the censer, put burning coals from the altar in it, place incense on it, and go quickly into the assembly and make atonement for them, for wrath has gone out from the Lord – the plague has begun!”

tn The verb is the Piel perfect with vav (ו) consecutive (וְכִפֶּר, vÿkhipper) to continue the instruction of the passage: “the priest shall make atonement,” meaning the priest is to make atonement for the sin (thus the present translation). This verb means “to expiate,” “to atone for,” “to pacify.” It describes the ritual events by which someone who was separated from the holy Lord God could find acceptance into his presence through the sacrificial blood of the substitutionary animal. See Lev 1 and Num 17:6-15.

tn Or “they will be forgiven.”
