The meaning of the phrase: without the permission of his masters

Question:
A slave who gathers the earnings of his masters without their permission. It is well known that a slave has one master, who may be a partner. When it says "without the permission of his masters," it means he seeks permission from someone other than the master, does it not?

Answer:
No, it refers to the generic term, because "slave" is a generic term. The meaning is slaves, meaning a slave that encompasses the generic term of a slave, i.e., a male slave. And slaves may have many masters. It is also possible that the meaning is that he has five, six, or ten masters, all of whom are partners, all from the same household, and all partners in him. It may be that each one of them has given him permission to act, meaning there is a good relationship between them regarding the disposal of wealth, where each one of them authorizes the other. There is no objection; if one of them gives him permission, then they have all given him permission.
