Isaiah 1:15-17 NIV

[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.
