And when you spread forth your hands, I will hide my eyes from you: yea, when you make many prayers, I will not hear: your hands are full of blood.
All Commentaries on Isaiah 1:15 Go To Isaiah 1
John Chrysostom
AD 407
One asks, “What if I have been overcome?” Then cleanse yourself. “How, in what manner?” Weep, groan, give alms, apologize to the one who is offended, reconcile him to yourself in so doing, wash clean your tongue so that you will not offend God more grievously. If someone were to fill his or her hands with dung and embrace your feet asking something of you, you would push that person away with your foot rather than listen. Then why do you draw near to God in such a manner, because in reality the tongue is the hand of the one who prays, and by it we embrace the legs of God.
