Isaiah 1:15

“And when ye spread forth your hands, &c.] That is, in prayer, this being a prayer gesture: hence the Targum paraphrases it, “and when the priests spread out their hands to pray for you.” I will hide mine eyes from you; will not look upon them, nor regard their prayer; (see <250342>Lamentations 3:42) yea, when ye make many prayers; as the Scribes and Pharisees did in Christ’s time, and thought to be heard for their much speaking, like the Gentiles, (<400607>Matthew 6:7) I will not hear; so as to give an answer, or fulfil their requests: the reason follows, your hands are full of blood; of the prophets of the Lord, of Christ and his followers, whom they put to death.”

“(Psa 66:18; Pro 28:9; Lam 3:43-44). spread . . . hands--in prayer (Kg1 8:22). Hebrew, "bloods," for all heinous sins, persecution of God's servants especially (Mat 23:35). It was the vocation of the prophets to dispel the delusion, so contrary to the law itself (Deu 10:16), that outward ritualism would satisfy God.”

“Ye spread forth your hands - This is an expression denoting the act of supplication. When we ask for help, we naturally stretch out our hands, as if to receive it. The expression therefore is equivalent to ‘when ye pray, or implore mercy.’ Compare Exodus 9:29; Exodus 17:11-12; 1 Kings 8:22. I will hide mine eyes ... - That is, I will not attend to, or regard your supplications. The Chaldee Paraphrase is, ‘When your priests expand their hands to pray for you.’ Your hands ... - This is given as a reason why he would not hear. The expression full of blood, denotes crime and guilt of a high order - as, in murder, the hands would be dripping in blood, and as the stain on the hands would be proof…”

“Blood - You are guilty of murder, and oppression. Isaiah 1:16”

“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.”

“when: Isa 59:2; Kg1 8:22, Kg1 8:54; Ezr 9:5; Job 27:8, Job 27:9, Job 27:20; Psa 66:18, Psa 134:2; Pro 1:28; Jer 14:12; Eze 8:17, Eze 8:18; Mic 3:4; Zac 7:13; Luk 13:25-28; Ti1 2:8 I will: Isa 58:7; Psa 55:1 make many prayers: Heb. multiply prayer, Mat 6:7, Mat 23:14 your hands: Isa 59:2, Isa 59:3; Jer 7:8-10; Mic 3:9-11 blood: Heb. bloods Isaiah 1:16”

“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…”
