Amos 5:21-24 (NRSV)
21 I hate, I despise your festivals, and I take no delight in your solemn assemblies. 22 Even though you offer me your burnt offerings and grain offerings, I will not accept them; and the offerings of well-being of your fatted animals I will not look upon. 23 Take away from me the noise of your songs; I will not listen to the melody of your harps. 24 But let justice roll down like waters, and righteousness like an ever-flowing stream.
