Leviticus 21:11-21

11 nor beside any dead person doth he come; for his father and for his mother he doth not defile himself;
12 nor from the sanctuary doth he go out, nor doth he pollute the sanctuary of his God, for the separation of the anointing oil of his God [is] on him; I [am] Jehovah.
13 `And he taketh a wife in her virginity;
14 widow, or cast out, or polluted one -- a harlot -- these he doth not take, but a virgin of his own people he doth take [for] a wife,
15 and he doth not pollute his seed among his people; for I [am] Jehovah, sanctifying him.'
16 And Jehovah speaketh unto Moses, saying,
17 `Speak unto Aaron, saying, No man of thy seed to their generations in whom there is blemish doth draw near to bring near the bread of his God,
18 for no man in whom [is] blemish doth draw near -- a man blind, or lame or dwarfed, or enlarged,
19 or a man in whom there is a breach in the foot, or a breach in the hand,
20 or hump-backed, or a dwarf, or with a mixture in his eye, or a scurvy person, or scabbed, or broken-testicled.
21 `No man in whom is blemish (of the seed of Aaron the priest) doth come nigh to bring near the fire-offerings of Jehovah; blemish [is] in him; the bread of his God he doth not come nigh to bring near.
