E fu portata una pietra e posta sulla bocca della fossa; il re la sigillò con il proprio anello e con l'anello dei suoi nobili, affinché nulla fosse mutato riguardo a Daniele.
Mishnah Kelim
Above them is one who had intercourse with a menstruant, for he defiles the bottom [bedding] upon which he lies as he does the top [bedding]. Above them is the issue of a zav, his spit, his semen and his urine, and the blood of a menstruant, for they convey impurity both by contact and by carrying. Above them is an object on which one can ride, for it conveys impurity even when it lies under a heavy stone. Above the object on which one can ride is that on which one can lie, for contact is the same as its carrying. Above the object on which one can lie is the zav, for a zav conveys impurity to the object on which he lies, while the object on which he lies cannot convey the same impurity to that upon which it lies.
