- Perhaps sin and guilt offerings were made, not just when one knew that one had committed a sin, but at other times too. For instance, for a priest who had to offer a sacrifice on the Day of Atonement and on the day he was appointed, a leper being cleansed from his previous illness and a mother who had just given birth. None of those people had committed any specific sins (that they knew of), but they were sinners by nature.
- Once again, God made provision for those who could not afford expensive animals for sacrifices but they did not get any less because they were not wealthy. (12:8; 14:21 – 23)
- God says if he puts a spreading mildew in a house, not ‘if there is a spreading mildew in a house’. (A reference to his sovereignty?)
- The uncleanliness of objects in a house with mildew was not a health issue. Things in a house with mildew did not become unclean unless a priest came to examine the house and they were in it then. God asked the people to remove things from a house to be inspected so they would not be pronounced unclean. If it were a health issue, then the things would be unclean whether the priest pronounced them so or not.
- The house also was not destroyed so long as the mildew could be removed (by taking away the affected parts).
- A leper had to go through a purification ritual when his illness was gone. A house that used to have mildew had to go through a purification ritual when the mildew is gone.
