Isaiah 58:3-8 New American Bible, Revised Edition (NABRE)

3. “Why do we fast, but you do not see it?afflict ourselves, but you take no note?”See, on your fast day you carry out your own pursuits,and drive all your laborers.

4. See, you fast only to quarrel and fightand to strike with a wicked fist!Do not fast as you do todayto make your voice heard on high!

5. Is this the manner of fasting I would choose,a day to afflict oneself?To bow one’s head like a reed,and lie upon sackcloth and ashes?Is this what you call a fast,a day acceptable to the Lord?

6. Is this not, rather, the fast that I choose:releasing those bound unjustly,untying the thongs of the yoke;Setting free the oppressed,breaking off every yoke?

7. Is it not sharing your bread with the hungry,bringing the afflicted and the homeless into your house;Clothing the naked when you see them,and not turning your back on your own flesh?

8. Then your light shall break forth like the dawn,and your wound shall quickly be healed;Your vindication shall go before you,and the glory of the Lord shall be your rear guard.
