English: "For it is good for him with you" — What is the force of "with you"? With you in food, with you in drink—so that you should not eat fine bread while he eats coarse bread, you drink aged wine while he drinks new wine, you sleep on cushions while he sleeps on straw. From here they said: Whoever acquires a Hebrew slave is as one who acquires a master for himself.
On the daf / in context: The standard of living of master and slave must be equal; the practical burden is so great that the master is said to have acquired a master over himself.
Type of Learning
Derash on the verse (Kiddushin) — equal living standards and the “master for himself” principle.
What Is Learned
A Hebrew slave must share the master’s standard of food, drink and lodging; acquiring such a slave is like acquiring a master over oneself.
