Leviticus 21

1 ¶ And the LORD said unto Moses, Speak unto the priests the sons of Aaron, and say unto them, There shall none be defiled for the dead among his people:
2 But for his kin, that is near unto him, that is, for his mother, and for his father, and for his son, and for his daughter, and for his brother,
3 And for his sister a virgin, that is nigh unto him, which hath had no husband; for her may he be defiled.

Handling and preparing a dead person for burial is limited to certain close relations.

4 But he shall not defile himself, being a chief man among his people, to profane himself.

However, a chief man was not to handle the dead.

5 They shall not make baldness upon their head, neither shall they shave off the corner of their beard, nor make any cuttings in their flesh.

These were obviously religious proscriptions. People apparently did these things for religious motives. Scarification is part of the modern fetish of Primitivism.

6 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.
7 They shall not take a wife that is a whore, or profane; neither shall they take a woman put away from her husband: for he is holy unto his God.

A priest could not marry a whore or a divorced woman.

8 Thou shalt sanctify him therefore; for he offereth the bread of thy God: he shall be holy unto thee: for I the LORD, which sanctify you, am holy.
9 And the daughter of any priest, if she profane herself by playing the whore, she profaneth her father: she shall be burnt with fire.

A priest’s daughter who was a whore had to be killed.

10 ¶ And he that is the high priest among his brethren, upon whose head the anointing oil was poured, and that is consecrated to put on the garments, shall not uncover his head, nor rend his clothes;
11 Neither shall he go in to any dead body, nor defile himself for his father, or for his mother;
12 Neither shall he go out of the sanctuary, nor profane the sanctuary of his God; for the crown of the anointing oil of his God is upon him: I am the LORD.

The priest is not to make the signs of mourning and grief, of tearing clothes or tending to the dead bodies of a close relative.

13 And he shall take a wife in her virginity.

The priest is to marry a virgin, a woman who has never had sex with a man.
14 A widow, or a divorced woman, or profane, or an harlot, these shall he not take: but he shall take a virgin of his own people to wife.

The priest is limited here as to what the condition is of the woman he is to marry.

15 Neither shall he profane his seed among his people: for I the LORD do sanctify him.

The priest is set apart for God. He must not do certain things that others are allowed to do.

16 ¶ And the LORD spake unto Moses, saying,
17 Speak unto Aaron, saying, Whosoever he be of thy seed in their generations that hath any blemish, let him not approach to offer the bread of his God.

The priest was not to have a handicap. This is not politically correct but it is true in regard to God’s rules for the priesthood. This is one reason not to take the doctrine of the Christian as a type of priest too far.

18 For whatsoever man he be that hath a blemish, he shall not approach: a blind man, or a lame, or he that hath a flat nose, or any thing superfluous,
19 Or a man that is brokenfooted, or brokenhanded,
20 Or crookbackt, or a dwarf, or that hath a blemish in his eye, or be scurvy, or scabbed, or hath his stones broken;
21 No man that hath a blemish of the seed of Aaron the priest shall come nigh to offer the offerings of the LORD made by fire: he hath a blemish; he shall not come nigh to offer the bread of his God.
22 He shall eat the bread of his God, both of the most holy, and of the holy.
23 Only he shall not go in unto the vail, nor come nigh unto the altar, because he hath a blemish; that he profane not my sanctuaries: for I the LORD do sanctify them.
24 And Moses told it unto Aaron, and to his sons, and unto all the children of Israel.

The handicapped man is to worship and partake of the bread of God, but he is not to enter into the vail. We will have no handicaps in our glorified bodies.
