7 Is it not to share your bread with the hungry and bring the homeless poor into your house; when you see the naked, to cover him, and not to hide yourself from your own flesh?
8 Then shall your light break forth like the dawn, and your healing shall spring up speedily; your righteousness shall go before you; the glory of the Lord shall be your rear guard. 9 Then you shall call, and the Lord will answer; you shall cry, and he will say, 'Here I am.' If you take away the yoke from your midst, the pointing of the finger, and speaking wickedness,

Commentary on Isaiah 58:3-12
(Read Isaiah 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.
