And it shall be forgiven all the congregation of the children of Israel,.... Which is repeated for the certainty of it, and for the sake of what follows:
and the stranger that sojourneth among them; the proselyte of righteousness; so the blessing of pardon, through the propitiatory sacrifice of Christ, comes upon believing Gentiles as well as Jews, Romans 4:9,
seeing all the people were in ignorance; both the congregation of Israel and the stranger; See Gill on Numbers 15:25.
This law was to apply not only to the children of Israel, but also to the stranger among them, "for (sc., it has happened) to the whole nation in mistake." As the sin extended to the whole nation, in which the foreigners were also included, the atonement was also to apply to the whole.
