'Consecration' in the Bible

Also thou shalt take of the ram the fat and the rump, and the fat that covereth the inwards, and the caul above the liver, and the two kidneys, and the fat that is upon them, and the right shoulder; for it is a ram of consecration:

And thou shalt take the breast of the ram of Aaron's consecration, and wave it for a wave offering before the LORD: and it shall be thy part.

And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, even of that which is for Aaron, and of that which is for his sons:

And thou shalt take the ram of the consecration, and seethe his flesh in the holy place.

They must eat those things by which atonement was made at the time of their ordination and consecration. An unauthorized person must not eat them, for these things are holy.

and if there be left of the flesh of the consecration or of the bread till the morning, then thou hast burned that which is left with fire; it is not eaten, for it is holy.
