Isaiah 1:12-17 NIV

[12] When you come to appear before me, who has asked this of you, this trampling of my courts? [13] Stop bringing meaningless offerings! Your incense is detestable to me. New Moons, Sabbaths and convocations—I cannot bear your worthless assemblies. [14] Your New Moon feasts and your appointed festivals I hate with all my being. They have become a burden to me; I am weary of bearing them. [15] When you spread out your hands in prayer, I hide my eyes from you; even when you offer many prayers, I am not listening. Your hands are full of blood! [16] Wash and make yourselves clean. Take your evil deeds out of my sight; stop doing wrong. [17] Learn to do right; seek justice. Defend the oppressed. Take up the cause of the fatherless; plead the case of the widow.
