"This chapter is based on Daniel 5 . Toward the close of Daniel's life great changes were taking place in the land to which, over threescore years before, he and his Hebrew companions had been carried captive. Nebuchadnezzar, “the terrible of the nations” ( Ezekiel 28:7 ), had died, and Babylon, “the praise of the whole earth” ( Jeremiah 51:41 ), had passed under the unwise rule of his successors, and gradual but sure dissolution was resulting. PK 522.1"
"Behold, therefore I will bring strangers upon thee, the terrible of the nations: and they shall draw their swords against the beauty of thy wisdom, and they shall defile thy brightness."
Ellen White directly references Ezekiel 28:7 in this passage.
"How is Sheshach taken! and how is the praise of the whole earth surprised! how is Babylon become an astonishment among the nations!"
Ellen White directly references Jeremiah 51:41 in this passage.
"Through the folly and weakness of Belshazzar, the grandson of Nebuchadnezzar, proud Babylon was soon to fall. Admitted in his youth to a share in kingly authority, Belshazzar gloried in his power and lifted up his heart against the God of heaven. Many had been his opportunities to know the divine will and to understand his responsibility of rendering obedience thereto. He had known of his grandfather's banishment, by the decree of God, from the society of men; and he was familiar with Nebuchadnezzar's conversion and miraculous restoration. But Belshazzar allowed the love of pleasure and self-glorification to efface the lessons that he should never have forgotten. He wasted the opportunities graciously granted him, and neglected to use the means within his reach for becoming more fully acquainted with truth. That which Nebuchadnezzar had finally gained at the cost of untold suffering and humiliation, Belshazzar passed by with indifference. PK 522.2"
"And thou his son, O Belshazzar, hast not humbled thine heart, though thou knewest all this;"
The EGW passage describes Belshazzar's failure to humble himself despite knowing the history of Nebuchadnezzar, which directly reflects the principle stated in Daniel 5:22. The EGW passage amplifies and explains the principle in the context of Belshazzar's life.
"He, that being often reproved hardeneth his neck, shall suddenly be destroyed, and that without remedy."
Both passages address the consequences of ignoring warnings and hardening one's heart. Proverbs 29:1 speaks of sudden destruction for those who repeatedly reject reproof, while the EGW passage describes Belshazzar's downfall due to his indifference to the lessons of the past. The connection is thematic, focusing on the danger of ignoring warnings.
