10 And if you give your bread to those in need of it, so that the troubled one may have his desire; then you will have light in the dark, and your night will be as the full light of the sun: 11 And the Lord will be your guide at all times; in dry places he will give you water in full measure, and will make strong your bones; and you will be like a watered garden, and like an ever-flowing spring. 12 And your sons will be building again the old waste places: you will make strong the bases of old generations: and you will be named, He who puts up the broken walls, and, He who makes ready the ways for use.

The Observance of the Sabbath

13 If you keep the Sabbath with care, not doing your business on my holy day; and if the Sabbath seems to you a delight, and the new moon of the Lord a thing to be honoured; and if you give respect to him by not doing your business, or going after your pleasure, or saying unholy words; 14 Then the Lord will be your delight; and I will put you on the high places of the earth; and I will give you the heritage of Jacob your father: for the mouth of the Lord has said it.

Matthew Henry's Commentary on Isaiah 58:10-14

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.

Commentary on Isaiah 58:13-14

(Read Isaiah 58:13-14)

The sabbath is a sign between God and his professing people; his appointing it is a sign of his favour to them; and their observing it is a sign of their obedience to him. We must turn from travelling on that day; from doing our pleasure on that holy day, without the control and restraint of conscience; or from indulging in the pleasures of sense. On sabbath days we must not follow our callings, or our pleasures. In all we say and do, we must put a difference between this day and other days. Even in Old Testament times the sabbath was called the Lord's day, and is fitly called so still; and for a further reason, it is the Lord Christ's day, Revelation 1:10. If we thus remember the sabbath day to keep it holy, we shall have the comfort and profit of it, and have reason to say, It is good to draw near to God.
