Leviticus 4:13-14

ACV(i) 13 And if the whole congregation of Israel err, and the thing be hid from the eyes of the assembly, and they have done any of the things which LORD has commanded not to be done, and are guilty, 14 when the sin by which they have sinned is known, then the assembly shall offer a young bullock for a sin offering, and bring it before the tent of meeting.
