10 and if you draw out your soul to the hungry, and satisfy the afflicted soul: then your light shall rise in darkness, and your obscurity be as the noonday; 11 and Yahweh will guide you continually, and satisfy your soul in dry places, and make strong your bones; and you shall be like a watered garden, and like a spring of water, whose waters don’t fail. 12 Those who shall be of you shall build the old waste places; you shall raise up the foundations of many generations; and you shall be called The repairer of the breach, The restorer of paths to dwell in.

The Observance of the Sabbath

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 of Yahweh honorable; and shall honor it, not doing your own ways, nor finding your own pleasure, nor speaking your own words: 14 then you shall 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 the mouth of Yahweh has spoken it.

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.
