Exodus 29:33-36 Catholic Public Domain Version (CPDV)

33. so that it may be an appeasing sacrifice, and so that the hands of those who offer may be sanctified. A stranger shall not eat from these, for they are holy.

34. And what may remain until morning, of the consecrated flesh or of the bread, you shall burn these remnants with fire. These shall not be eaten, because they have been sanctified.

35. All that I have instructed you concerning Aaron and his sons, you shall do. For seven days shall you consecrate their hands,

36. and you shall offer a calf for sin on each day, as an atonement. And you shall cleanse the altar when you will have immolated the victim of expiation, and you shall anoint it for sanctification.
