What level of impurity does an object contract when a zav lies upon it?
Halacha 1 states: 'Any article on which one lies or rides to which a zav or the like imparted impurity becomes a primary source of impurity according to Scriptural Law.'
Question 2
What is madaf impurity?
Halacha 2 states: 'All keilim that rest above a zav or the like are called madaf. They are considered as articles that he touches.'
Question 3
Does midras impurity apply after the death of an impure person?
Halacha 3 explicitly states that a zav, zavah, nidah, woman after childbirth, or metzora imparts impurity to objects they lied or rode upon even after their death.
Question 4
If a zav sits above foods, liquids, and keilim NOT designed for lying or sitting without touching them, what is their status?
Halacha 5 rules: 'When food, liquids, and keilim that are not made to lie, sit, or ride upon were below other articles and a zav or the like sat above them without touching them, they are all pure.'
Question 5
If a zav carries an object that is designed for lying on his shoulders without actually lying on it, does the object contract midras impurity?
Halacha 4 explains: midras impurity does not require the person to actually touch the object — even being moved by or resting on the person through clothing is sufficient, as long as the object could be used for resting.
