"Cry aloud, don't spare, lift up your voice like a trumpet, and declare to my people their disobedience, and to the house of Jacob their sins.
2Yet they seek me daily, and delight to know my ways. As a nation that did righteousness, and didn't forsake the ordinance of their God, they ask of me righteous judgments. They delight to draw near to God.
3'Why have we fasted,' they say, 'and you don't see? Why have we afflicted our soul, and you don't notice?' Behold, in the day of your fast you find your own pleasure, and oppress all your laborers.
4Behold, you fast for strife and contention, and to strike with the fist of wickedness. You don't fast today so as to make your voice to be heard on high.
5Is such the fast that I have chosen? The day for a man to afflict his soul? Is it to bow down his head as a rush, and to spread sackcloth and ashes under him? Will you call this a fast, and an acceptable day to Yahweh?
6Isn't this the fast that I have chosen: to release the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and that you break every yoke?
7Isn't it to distribute your bread to the hungry, and that you bring the homeless poor into your house? When you see the naked, that you cover him; and that you not hide yourself from your own flesh?
8Then your light will break out as the morning, and your healing will spring out quickly. Your righteousness will go before you, and Yahweh's glory will be your rear guard.
9Then you will call, and Yahweh will answer. You will cry, and he will say, 'Here I am.' If you take away from among you the yoke, the pointing of the finger, and speaking wickedness;
10and if you pour out your soul to the hungry, and satisfy the afflicted soul: then your light will rise in darkness, and your obscurity will be as the noonday.
11Yahweh will guide you continually, satisfy your soul in dry places, and make your bones strong. You will be like a watered garden, and like a spring of water whose waters don't fail.
12Those who will be of you will build the old waste places. You will raise up the foundations of many generations. You will be called Repairer of the Breach, Restorer of Paths with Dwellings.
13"If you turn away your foot from the Sabbath, from doing your pleasure on my holy day; and call the Sabbath a delight, and the holy day of Yahweh honorable; and honor it, not doing your own ways, nor finding your own pleasure, nor speaking your own words:
14then you will delight yourself in Yahweh, and I will make you to ride on the high places of the earth, and I will feed you with the heritage of Jacob your father; for Yahweh's mouth has spoken it."

Summary

Isaiah 58 confronts Israel's hollow religious practice — they fast and observe rituals while continuing to oppress workers, quarrel, and ignore the poor. God declares that the true fast He desires is not outward religious performance but active justice: freeing the oppressed, feeding the hungry, sheltering the homeless, and clothing the naked. The chapter closes with a call to honor the Sabbath genuinely, promising that those who do will experience God's guidance, restoration, and delight.

Themes

  • True religion versus empty ritual
  • Justice and care for the poor and oppressed
  • Light, healing, and restoration as fruits of genuine obedience
  • The Sabbath as delight and honor rather than burden
  • God's responsiveness to authentic seeking

Key verses

  • Isa 58:6 — “Isn't this the fast that I have chosen: to release the bonds of wickedness, to undo the straps of the yoke, to let the oppressed go free, and that you break every yoke?”
  • Isa 58:7 — “Isn't it to distribute your bread to the hungry, and that you bring the homeless poor into your house? When you see the naked, that you cover him; and that you not hide yourself from your own flesh?”
  • Isa 58:8 — “Then your light will break out as the morning, and your healing will spring out quickly. Your righteousness will go before you, and Yahweh's glory will be your rear guard.”

Context & background

Isaiah 58 is addressed to the Jewish community, likely in the context of the Babylonian exile or its aftermath, when the people had returned to the land of modern-day Israel from captivity in what is now central Iraq. Fasting was a significant religious practice in ancient Israel, associated with mourning, repentance, and petition before God. The tension the prophet identifies — meticulous religious observance coexisting with social injustice — was a recurring problem throughout Israel's history and is addressed by multiple prophets. The Sabbath reference at the chapter's close connects personal holiness with communal restoration, reinforcing that covenant faithfulness is both vertical (toward God) and horizontal (toward neighbor).

Cross-references

  • Amos 5:21-24 — God declares He hates Israel's feasts and offerings when justice is absent, calling instead for justice to roll like a river
  • Isaiah 61:1-2 — The Servant anointed to proclaim good news to the poor, liberty to captives — echoing the justice themes of chapter 58
  • James 1:27 — "Pure religion and undefiled before our God and Father is this: to visit the fatherless and widows in their affliction, and to keep oneself unstained by the world."
  • Matthew 25:35-40 — Jesus identifies care for the hungry, stranger, and naked as service done directly to Him
  • Micah 6:6-8 — "What does Yahweh require of you but to do justly, to love mercy, and to walk humbly with your God?"
