"Six years shall he serve": I might think, both demeaning or non-demeaning service; it is, therefore, written (Ibid. 40) "as a hired laborer or a bound laborer." Just as you may not deflect a hired laborer from his trade, so, a Hebrew man-servant. From here they ruled that one may not set him at a trade which is public-oriented, such as that of a tailor, a bath-house attendant, a barber, a butcher, or a banker. R. Yossi says: If that were his trade, he may keep him at it, but his master may not alter it (for a different form of public service.)
