פירוש על ברכות 31:14

Singer, pp. 44 ff.

To act as Precentor, because this would interfere with their duty to their employer.

A Kohen (see Glossary, s.v.) has the privilege to "raise his hands" in the course of the Service to pronounce the priestly benediction (Num. vi. 24-26) ; but if a labourer, he must not do so. In Talmudical times, this was done daily ; but now it is usually reserved for Festivals only, the Precentor pronouncing the benediction in the daily Service (Singer, p. 53). Cf. J. E. III. p. 244.
