John Calvin Commentary Leviticus 21:9

"And the daughter of any priest, if she profane herself by playing the harlot, she profaneth her father: she shall be burnt with fire." — Leviticus 21:9 (ASV)

And the daughter of any priest. The moderation and chastity (required in the priest¹⁹¹) also extend to his daughter. By synecdoche, this means that all matters of good discipline are included under this one principle: namely, that his children should be educated in the study of virtue and in decent and pure morality.

A heavy punishment is prescribed for a priest’s daughter if she engages in prostitution, because sacrilege would be combined with her disgraceful sexual immorality.

It is, however, a serious crime to violate God’s sanctuary. If the priest had tolerated such an iniquity in his daughter, he could not have been a strict avenger of the same wickedness in others. Indeed, he would not have been free to punish crimes unless he had first made a beginning in his own household.
