"Had Israel remained true to God, this glorious building would have stood forever, a perpetual sign of God's especial favor to His chosen people. “The sons of the stranger,” God declared, “that join themselves to the Lord, to serve Him, and to love the name of the Lord, to be His servants, everyone that keepeth the Sabbath from polluting it, and taketh hold of My covenant; even them will I bring to My holy mountain, and make them joyful in My house of prayer: their burnt offerings and their sacrifices shall be accepted upon Mine altar; for Mine house shall be called an house of prayer for all people.” Isaiah 56:6, 7 . PK 46.1"
"Also the sons of the stranger, that join themselves to the Lord, to serve him, and to love the name of the Lord, to be his servants, every one that keepeth the sabbath from polluting it, and taketh hold of my covenant;"
The EGW passage directly quotes Isaiah 56:6, making it a clear and intentional allusion.
"Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people."
The EGW passage directly quotes Isaiah 56:7, making it a clear and intentional allusion.
"In connection with these assurances of acceptance, the Lord made very plain the path of duty before the king. “As for thee,” He declared, “if thou wilt walk before Me, as David thy father walked, and do according to all that I have commanded thee, and shalt observe My statutes and My judgments; then will I establish the throne of thy kingdom, according as I have covenanted with David thy father, saying, There shall not fail thee a man to be ruler in Israel.” 2 Chronicles 7:17, 18 . PK 46.2"
"And if thou wilt walk before me, as David thy father walked, in integrity of heart, and in uprightness, to do according to all that I have commanded thee, and wilt keep my statutes and my judgments:"
EGW directly quotes 2 Chronicles 7:17,18, which is a parallel account to 1 Kings 9:4. The wording is nearly identical, making this an explicit allusion.
"And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever."
Both passages discuss the establishment of the kingdom and throne. While EGW quotes 2 Chronicles 7:17,18, the underlying promise echoes the Davidic covenant in 2 Samuel 7:16.
