"God has revealed in His law the principles that underlie all true prosperity both of nations and of individuals. “This is your wisdom and your understanding,” Moses declared to the Israelites of the law of God. “It is not a vain thing for you; because it is your life.” Deuteronomy 4:6 ; 32:47 . The blessings thus assured to Israel are, on the same conditions and in the same degree, assured to every nation and every individual under the broad heavens. Ed 174.1"
"Keep therefore and do them; for this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes, and say, Surely this great nation is a wise and understanding people."
EGW directly quotes Deuteronomy 4:6, making this a clear and explicit allusion.
"For it is not a vain thing for you; because it is your life: and through this thing ye shall prolong your days in the land, whither ye go over Jordan to possess it."
EGW directly quotes Deuteronomy 32:47, making this a clear and intentional reference.
"The power exercised by every ruler on the earth is Heaven-imparted; and upon his use of the power thus bestowed, his success depends. To each the word of the divine Watcher is, “I girded thee, though thou hast not known Me.” Isaiah 45:5 . And to each the words spoken to Nebuchadnezzar of old are the lesson of life: “Break off thy sins by righteousness, and thine iniquities by showing mercy to the poor; if it may be a lengthening of thy tranquility.” Daniel 4:27 . Ed 174.2"
"I am the Lord, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:"
Ellen White directly references Isaiah 45:5 in this passage.
"Wherefore, O king, let my counsel be acceptable unto thee, and break off thy sins by righteousness, and thine iniquities by shewing mercy to the poor; if it may be a lengthening of thy tranquillity."
Ellen White directly references Daniel 4:27 in this passage.
"And he changeth the times and the seasons: he removeth kings, and setteth up kings: he giveth wisdom unto the wise, and knowledge to them that know understanding:"
Both passages touch on God's sovereignty over rulers. Daniel 2:21 states God's power to remove and set up kings, while the EGW passage discusses the Heaven-imparted power of rulers. The connection is thematic, focusing on God's control over earthly leadership.
