Isaiah 1:14-16

14Your 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.

15When 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!

16Wash and make yourselves clean. Take your evil deeds out of my sight; stop doing wrong.
