Numbers 15:25

And the priest shall make an atonement for all the congregation of the children of Israel ;.... By offering a sin offering for them, a type of Christ, the propitiation not only for the sins of the people among the Jews, but throughout the whole world, 1 John 2:2 ,

and it shall be forgiven them ; as the sins of the Lord's people are forgiven them through the blood of Christ, and on account of his stoning sacrifice and satisfaction made for them:

for it is ignorance ; a sin of ignorance, for which reason Christ pleads for pardon on the foot of his sacrifice, and his people receive it, Luke 23:34 ; for that this sin was forgiven on the score of a sacrifice appears by what follows:

and they shall bring their offering, a sacrifice made by fire unto the Lord ; the bullock for the burnt offering:

and their sin offering before the Lord, for their ignorance ; a kid of the goats.
