Ісая 1:15

Their self-righteousness, so far as it rested upon sacrifices and festal observances, was now put to shame, and the last inward bulwark of the sham holy nation was destroyed: "And if ye stretch out your hands, I hide my eyes from you; if ye make ever so much praying, I do not hear: your hands are full of blood." Their praying was also an abomination to God. Prayer is something common to man: it is the interpreter of religious feeling, which intervenes and mediates between God and man; (Note: The primary idea of hithpallel and tephillah is not to be obtained from Deu 9:18 and Ezr 10:1, as Dietrich and Frst suppose, who make hithpallel equivalent to hithnappel, to throw one's self down; but from Sa1 2:25, "If a man sin against a man, the authorities right him" (וּפללו אלהים: it is quite a mistake to maintain that Elohim cannot have this meaning), i.e., they can set right the relation which he has disturbed. "But if one sin against Jehovah, who shall mediate for him (מי יתפּלּל־לו, quis intercedat pro eo)?" We may see from this that prayer is regarded as mediation, which sets right and establishes fellowship; and hithpallel signifies to make one's self a healer of divisions, or to settle for one's self, to strive after a settlement (sibi, pro se, intercedere: cf., Job 19:16, hithchannen, sibi propitium facere; Job 13:27, hithchakkah, sibi insculpere, like the Arabic ichtatta, to bound off for one's self).) it is the true spiritual sacrifice. The law contains no command to pray, and, with the exception of Deut 26, no form of prayer. Praying is so natural to man as man, that there was no necessity for any precept to enforce this, the fundamental expression of the true relation to God. The prophet therefore comes to prayer last of all, so as to trace back their sham-holiness,…

The first verse of this chapter is intended for a title to the whole book, and it is probable that this was the first sermon that this prophet was appointed to publish and to affix in writing (as Calvin thinks the custom of the prophets was) to the door of the temple, as with us proclamations are fixed to public places, that all might read them (Hab 2:2), and those that would might take out authentic copies of them, the original being, after some time, laid up by the priests among the records of the temple. The sermon which is contained in this chapter has in it, I. A high charge exhibited, in God's name, against the Jewish church and nation, 1. For their ingratitude (Isa 1:2, Isa 1:3). 2. For their incorrigibleness (Isa 1:5). 3. For the universal corruption and degeneracy of the people (Isa 1:4, Isa 1:6, Isa 1:21, Isa 1:22). 4. For the perversion of justice by their rulers (Isa 1:23). II. A sad complaint of the judgments of God, which they had brought upon themselves by their sins, and by which they were brought almost to utter ruin (Isa 1:7-9). III. A just rejection of those shows and shadows of religion which they kept up among them, notwithstanding this general defection and apostasy (Isa 1:10-15). IV. An earnest call to repentance and reformation, setting before them life and death, life if they compiled with the call and death if they did not (Isa 1:16-20). V. A threatening of ruin to those that would not be reformed (Isa 1:24, Isa 1:28-31). VI. A promise of a happy reformation at last, and a return to their primitive purity and prosperity (Isa 1:25-27). And all this is to be applied by us, not only to the communities we are members of, in their public interests, but to the state of our own souls.

1:15 I will not look . . . I will not listen: The Lord does not respond to prayer offered from a life of persistent wickedness. In this case, God charged the people with perverting his laws in order to practice violent injustice toward innocent victims.
