'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.

And he brought the other ram, the ram of consecration: and Aaron and his sons laid their hands upon the head of the ram.

And Moses took the breast, and waved it for a wave offering before the LORD: for of the ram of consecration it was Moses' part; as the LORD commanded Moses.

And ye shall not go out of the door of the tabernacle of the congregation in seven days, until the days of your consecration be at an end: for seven days shall he consecrate you.

He shall not make himself unclean for his father, or for his mother, for his brother, or for his sister, when they die: because the consecration of his God is upon his head.

And if any man die very suddenly by him, and he hath defiled the head of his consecration; then he shall shave his head in the day of his cleansing, on the seventh day shall he shave it.
