Numbers Chapter 15, Verse 24
From BibleWiki
24: Then it shall be, if ought be committed by ignorance without
the knowledge of the congregation, that all the congregation
shall offer one young bullock for a burnt offering, for a
sweet savour unto the LORD, with his meat offering, and his
drink offering, according to the manner, and one kid of the
goats for a sin offering.
24: And the multitude have forgotten to do it: they shall offer a
calf out of the herd, a holocaust for a most sweet savour to the Lord,
and the sacrifice and libations thereof, as the ceremonies require, and
a buck goat for sin:
24: then it shall come to pass, if a trespass be committed unwillingly, unknown to the congregation, then shall all the congregation offer a calf of the herd without blemish for a whole-burnt-offering of sweet savour to the Lord, and its meat-offering and its drink-offering according to the ordinance, and one kid of the goats for a sin-offering.
