The seventh [year] cancels loans, [whether they are recorded] in a document or not [recorded] in a document. It does not cancel shop credit, but if he converted it into a loan it is canceled. R’ Yehudah says: The earlier [debt] is canceled. The wage of a hired person is not canceled; but if he converted it into a loan, it is canceled. R’ Yose says: Any work which ceases in the seventh [year] is canceled, but that which does not cease in the seventh [year] is not canceled.
