"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 . PK 678.1"
"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, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:"
EGW directly quotes Isaiah 58:13.
"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."
EGW directly quotes Isaiah 58:14.
"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. In clear, distinct lines they are to present the necessity of obedience to all the precepts of the Decalogue. Constrained by the love of Christ, they are to co-operate with Him in building up the waste places. They are to be repairers of the breach, restorers of paths to dwell in. See verse 12 . PK 678.2"
"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."
EGW directly quotes and applies Isaiah 58:12 to the work of God's people.
"Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it."
EGW connects the Sabbath commandment (Exodus 20:8-11) with the idea of the Sabbath as a memorial of creation and a reminder of God's power, which is a central theme in both passages.
