      Isa 58:1-14. REPROOF OF THE JEWS FOR THEIR DEPENDENCE ON MERE OUTWARD FORMS OF WORSHIP.

      1. aloud--Hebrew, "with the throat," that is, with full voice, not merely from the lips (1Sa 1:13). Speak loud enough to arrest attention.
      my people--the Jews in Isaiah's time, and again in the time of our Lord, more zealous for externals than for inward holiness. ROSENMULLER thinks the reference to be to the Jews in the captivity practising their rites to gain God's favor and a release; and that hence, sacrifices are not mentioned, but only fasting and Sabbath observance, which they could keep though far away from the temple in Jerusalem. The same also applies to their present dispersion, in which they cannot offer sacrifices, but can only show their zeal in fastings, &c. Compare as to our Lord's time, Mt 6:16, 23; Lu 18:12.
