'Inadvertently' in the Bible

And if the whole assembly of Israel sin inadvertently, and the thing be hid from the eyes of the congregation, and they do somewhat against any of all the commandments of Jehovah in things which should not be done, and are guilty;

And he shall bring a ram without blemish out of the small cattle, according to thy valuation, as trespass-offering, unto the priest; and the priest shall make atonement for him concerning his inadvertence wherein he sinned inadvertently, and knew it not, and it shall be forgiven him.
