Isaiah 58:3-4

They say, ‘To honor you we had special days when we fasted, but you didn’t see. We humbled ourselves to honor you, but you didn’t notice.’ ” But the LORD says, “You do what pleases yourselves on these special days, and you are unfair to your workers. On these special days when you fast, you argue and fight and hit each other with your fists. You cannot do these things as you do now and believe your prayers are heard in heaven.
