Now if you stray unintentionally and do not obey all these commandments that the LORD has spoken to Moses—
22. And if ye have erred. He teaches by what kind of sacrifice the sins of the whole people or of each individual are to be expiated, although he enumerates only two of the four classes which are mentioned in Leviticus; for a special atonement is there enjoined both on the priest and the ruler.
We have here the laws concerning sacrifices for sins of ignorance; the Jews understand it of idolatry, or false worship, through the error of their teachers. The case here supposed is that they had not observed all these commandments, Num 15:22, Num 15:23.
Commenting on Numbers 15:22-29
Even all that the Lord hath commanded you by the hand of Moses,.... Recorded in this book and the two preceding, whether of a moral, ceremonial, or judicial kind; the whole body of laws given to the people of Israel from the Lord by Moses: from the day that the Lord commanded Moses, and henceforward among your generations; all that he had commanded, or should hereafter command.
