58:3-12 A fast is a day to afflict the soul; if it does not express true sorrow for sin, and does not promote the putting away of sin, it is not a fast. These professors had shown sorrow on stated or occasioned fasts. But they indulged pride, covetousness, and malignant passions. To be liberal and merciful is more acceptable to God than mere fasting, which, without them, is vain and hypocritical. Many who seem humble in God's house, are hard at home, and harass their families. But no man's faith justifies, which does not work by love. Yet persons, families, neighbourhoods, churches, or nations, show repentance and sorrow for sin, by keeping a fast sincerely, and, from right motives, repenting, and doing good works. The heavy yoke of sin and oppression must be removed. As sin and sorrow dry the bones and weaken the strongest human constitution; so the duties of kindness and charity strengthen and refresh both body and mind. Those who do justly and love mercy, shall have the comfort, even in this world. Good works will bring the blessing of God, provided they are done from love to God and man, and wrought in the soul by the Holy Spirit.

6. loose … bands of wickedness—that is, to dissolve every tie wherewith one has unjustly bound his fellow men (Le 25:49, &c.). Servitude, a fraudulent contract, &c.

undo … heavy burdens—Hebrew, "loose the bands of the yoke."

oppressed—literally, "the broken." The expression, "to let go free," implies that those "broken" with the yoke of slavery, are meant (Ne 5:10-12; Jer 34:9-11, 14, 16). Jerome interprets it, broken with poverty; bankrupt.
