Leviticus 21:21-23

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.

²²'Bread of his God — of the most holy things, and of the holy things — he doth eat;

²³only, unto the vail he doth not enter, and unto the altar he doth not draw nigh; for blemish is in him; and he doth not pollute My sanctuaries; for I am Jehovah, sanctifying them.'
