What Does Isaiah 58:6 Mean?

God now defines the fast He chooses: "to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that ye break every yoke." Four parallel phrases emphasize comprehensive liberation. "Bands of wickedness" are cords of injustice binding people in oppression. "Heavy burdens" are the crushing weights of exploitation—economic, social, or political. "Let the oppressed go free" uses the Hebrew ratsats (oppressed/crushed), describing those ground down by injustice. "Break every yoke" employs the imagery of slavery—removing the wooden beam that harnessed oxen. True fasting manifests in social justice: freeing slaves, canceling unjust debts, ending exploitation, reforming oppressive structures. This is not works-righteousness but the fruit of genuine repentance. From a Reformed perspective, this illustrates that justification by faith alone necessarily produces sanctification. Those truly regenerated demonstrate transformed affections, seeking God's glory through love of neighbor. This anticipates Jesus' proclamation of His mission: "to preach deliverance to the captives...to set at liberty them that are bruised" (Luke 4:18), and James's definition of pure religion as caring for orphans and widows (James 1:27).
