And they that shall be of thee shall build the old waste places: thou shalt raise up the foundations of many generations; and thou shalt be called, The repairer of the breach, The restorer of paths to dwell in. Isaiah 58:12
The prophet here describes a people who, in a time of general departure from truth and righteousness, are seeking to restore the principles that are the foundation of the kingdom of God. They are repairers of a breach that has been made in God's law--the wall that He has placed around His chosen ones for their protection, and obedience to whose precepts of justice, truth, and purity is to be their perpetual safeguard.
In words of unmistakable meaning the prophet points out the specific work of this remnant people who build the wall. "If thou turn away thy foot from the Sabbath, from doing thy pleasure on My holy day; and call the Sabbath a delight, the holy of the Lord, honorable; and shalt honor Him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: then shalt thou delight thyself in the Lord; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the Lord hath spoken it" (Isaiah 58:13, 14). (Prophets and Kings, 678)
Reflection: God's remnant people, standing before the world as reformers, are to show that the law of God is the foundation of all enduring reform and that the Sabbath of the fourth commandment is to stand as a memorial of creation, a constant reminder of the power of God. (Prophet and Kings, 678)
