Numbers 15:24-26

²⁴If you or they sin by forgetting to obey these instructions and none of the Israeli people realize that they were doing that, one young bull as an offering for all the people must be brought to the priest. That will be pleasing to me when it is burned on the altar. They must also bring to me a grain offering and an offering of wine, and a male goat, to be sacrificed to enable me to forgive them for the sins they have committed.

²⁵By offering these sacrifices, the priest will make atonement for all of you Israeli people. Then, as a result of their bringing to me an offering to be burned on the altar, ◄you will be forgiven/I will forgive you►, because you sinned without realizing that you were sinning.

²⁶You Israeli people and the foreigners who are living among you will all be forgiven.
