Leviticus 21:15 Meaning and Commentary

Leviticus 21:15

Neither shall he profane his seed among his people
By marrying any such persons, whereby his children, born of them, would lie under disgrace, and be unfit to succeed him in the priesthood, or by marrying among mean persons, or by marrying them to such as were unlawful, and would be a disparagement to them:

for I the Lord do sanctify him;
separate him from all others, to the high and sacred office of the high priesthood, and am concerned for his honour and holiness; and therefore it became him to observe these laws and rules, and abstain from such disagreeable marriages.

14 A widow, or one whose husband has put her away, or a common woman of loose behaviour, may not be the wife of a priest; but let him take a virgin from among his people.

15 And he may not make his seed unclean among his people, for I the Lord have made him holy.

16 And the Lord said to Moses,

17 Say to Aaron, If a man of your family, in any generation, is damaged in body, let him not come near to make the offering of the bread of his God.
