Isaiah.
Chapter 58.
Give a roar from the throat! Don't hold back! Shout out like a trumpet! Announce to my people how rebellious they are; denounce to the descendants of Jacob their sins. 
Every day they come to me, pleased to know my ways as if they were a nation that does what is right and follows the laws of their God! They ask me to treat them right; they like to be close to their God. 
“Didn't you see that we fasted?” they ask. “Didn't you notice how we denied ourselves?” That's because whenever you fast you still do whatever you want, and you treat your workers badly. 
Can't you see that when you're fasting you quarrel and argue, and end up having a vicious fistfight? When you fast like this you can't expect your prayers to be heard on high! 
Is this the kind of fast I want when people act out their humility by bowing their heads down like a reed and by lying around in sackcloth and ashes? Is that what you call a fast, a day the Lord appreciates? 
No, this is the fast I want: set free those who have been unjustly imprisoned, untie the cords of the yoke used to burden people, set free those who are oppressed, and get rid of every form of abuse. 
Share your food with the hungry, take the poor and homeless into your house. When you see people naked, give them clothes, and don't reject your own relatives. 
Then your light will shine out like the dawn, and you will be healed quickly; your salvation will go before you, and the glory of the Lord will go behind you. 
Then when you call, the Lord will answer; when you cry out for help, the Lord will say, “I'm here.” If you get rid of oppression among you, if you stop pointing the finger and slandering others, 
if you dedicate yourselves to helping the hungry and give the poor what they need, then your light will shine out in the darkness, and your night will be like the sun at noon. 
The Lord will always lead you; he will give you all you need in you in a desolate land; he will make you strong again. You will be like a well-watered garden, like a spring that never runs dry. 
Some among you will rebuild the ancient ruins; you will restore generations-old foundations. You will be called the Repairer of the Break in the Wall, the Restorer of Life's Pathways. 
If you make sure you don't break the Sabbath by doing whatever you please on my holy day, if you say the Sabbath brings you pleasure and the Lord's day is to be honored, and if you honor it by leaving aside your own ways, by not doing whatever you please, and by avoiding chatting about ordinary things, 
then you'll find the Lord is the one who truly makes you happy, and I will give you high positions on the earth and give you what I promised to Jacob, your forefather. I, the Lord, have spoken.
