Leviticus 4
13 Ref And if all the people of Israel do wrong, without anyone's knowledge; if they have done any of the things which by the Lord's order are not to be done, causing sin to come on them;
14 Ref When the sin which they have done comes to light, then let all the people give an ox for a sin-offering, and take it before the Tent of meeting.
15 Ref And let the chiefs of the people put their hands on its head before the Lord, and put the ox to death before the Lord.
