The heavy punishments which had already overtaken the people might naturally give rise to apprehensions for the future, especially in view of the fact that on the approaching entrance into Canaan the complete observance of the Law in all its details would become imperative on them. To meet such apprehensions a distinction is emphatically drawn between sins of ignorance (Leviticus 4:13 ff) and those of presumption Numbers 15:30-31. The passage deals separately with imperfections of obedience which would be regarded as attaching to the whole nation Numbers 15:22-26, and those of individuals Numbers 15:27-30.

And if ye have erred,.... Gone astray from the law of God, and any of its precepts; every sin is an error, a missing of the mark, a wandering from the way of God's commandments. Jarchi, and the Jews in general, interpret this of idolatry, but it rather respects any deviation from the law, moral or ceremonial, especially the latter:

and not observed all these commandments which the Lord hath spoken unto Moses; in this chapter, more particularly concerning the meat offerings and drink offerings, and the quantity of them, to be brought along with their burnt offerings and peace offerings, and concerning the cake of the first dough to be heaved before the Lord and given to the priest.

And if ye {f} have erred, and not observed all these commandments, which the LORD hath spoken unto Moses,

(f) By oversight or ignorance, read Le 4:2,13.

15:22 All these commandments - Those now spoken of, which concern the outward service of God, or the rites or ceremonies belonging to it. And herein principally this law may seem to differ from that Lev 4:13, which speaks of some positive miscarriage, or doing that which ought not to have been done, about the holy things of God; whereas this speaks only of an omission of something which ought to have been done about holy ceremonies.

22. if ye have erred, and not observed all these commandments, &c.-respecting the performance of divine worship, and the rites and ceremonies that constitute the holy service. The law relates only to any omission and consequently is quite different from that laid down in Le 4:13, which implies a transgression or positive neglect of some observances required. This law relates to private parties or individual tribes; that to the whole congregation of Israel.

15:22-29 Though ignorance will in a degree excuse, it will not justify those who might have known their Lord's will, yet did it not. David prayed to be cleansed from his secret faults, those sins which he himself was not aware of. Sins committed ignorantly, shall be forgiven through Christ the great Sacrifice, who, when he offered up himself once for all upon the cross, seemed to explain one part of the intention of his offering, in that prayer, Father, forgive them, for they know not what they do. It looked favourably upon the Gentiles, that this law of atoning for sins of ignorance, is expressly made to extend to those who were strangers to Israel.
