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.
