Leviticus 22:2

All the firstling males that come of thy herd and of thy flock thou shalt sanctify unto the Lord thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.

And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the Lord.

That thou shalt set apart unto the Lord all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the Lord’s.

And it shall be upon Aaron’s forehead, that Aaron may bear the iniquity of the holy things, which the children of Israel shall hallow in all their holy gifts; and it shall be always upon his forehead, that they may be accepted before the Lord.

And ye shall not swear by my name falsely, neither shalt thou profane the name of thy God: I am the Lord.

Neither shall ye profane my holy name; but I will be hallowed among the children of Israel: I am the Lord which hallow you,

And ye shall bear no sin by reason of it, when ye have heaved from it the best of it: neither shall ye pollute the holy things of the children of Israel, lest ye die.

Thus shall ye separate the children of Israel from their uncleanness; that they die not in their uncleanness, when they defile my tabernacle that is among them.

And I will set my face against that man, and will cut him off from among his people; because he hath given of his seed unto Molech, to defile my sanctuary, and to profane my holy name.

They shall be holy unto their God, and not profane the name of their God: for the offerings of the Lord made by fire, and the bread of their God, they do offer: therefore they shall be holy.

Say unto them, Whosoever he be of all your seed among your generations, that goeth unto the holy things, which the children of Israel hallow unto the Lord, having his uncleanness upon him, that soul shall be cut off from my presence: I am the Lord. What man soever of the seed of Aaron is a leper, or hath a running issue; he shall not eat of the holy things, until he be clean. And whoso toucheth any thing that is unclean by the dead, or a man whose seed goeth from him; Or whosoever toucheth any creeping thing, whereby he may be made unclean, or a man of whom he may take uncleanness, whatsoever uncleanness he hath; The soul which hath touched any such shall be unclean until even, and shall not eat of the holy things, unless he wash his flesh with water.

He shall separate himself from wine and strong drink, and shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any liquor of grapes, nor eat moist grapes, or dried. All the days of his separation shall he eat nothing that is made of the vine tree, from the kernels even to the husk. All the days of the vow of his separation there shall no razor come upon his head: until the days be fulfilled, in the which he separateth himself unto the Lord, he shall be holy, and shall let the locks of the hair of his head grow. All the days that he separateth himself unto the Lord he shall come at no dead body. 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. All the days of his separation he is holy unto the Lord.
