Daniel 4:8
But at the last Daniel came in before me, whose name was Belteshazzar, according to the name of my god, and in whom is the spirit of the holy gods: and before him I told the dream, saying, But at the last Daniel came in before me, whose name was Belteshazzar, according to the name of my god, and in whom is the spirit of the holy gods: and before him I told the dream, saying,
Daniel 4:8 comes at the point where Daniel is brought in last to hear another dream that God gave to Nebuchadnezzar, recorded in Daniel 4. That dream was given after Nebuchadnezzar had lost the holy impression made upon his mind by the deliverance of the three Hebrews, when he saw the form of the Fourth with them in the fiery furnace and acknowledged their God as the living God, because he did not continue to walk in the light he had received. The dream Daniel was called to hear tells of a lofty tree planted in the earth that sheltered the flocks and herds from the mountains and hills and lodged the birds of the air in its branches. The tree represents Nebuchadnezzar's greatness and prosperity, with the nations gathered under his sovereignty and his kingdom firmly established in the hearts of his loyal subjects.
The record is given as a warning against self-sufficiency, not to trust in oneself or in one's own wisdom or to rely on human strength. God gave Nebuchadnezzar light to guide him, and disregarding that light meant losing its benefits. The same case shows bringing into God's work and vineyard principles He will not sustain or favor, carrying on His work by the wisdom of human minds rather than as He requires.
Nebuchadnezzar's experience included banishment, conversion, and restoration, which Belshazzar knew. That experience taught humility and obedience to God, lessons Belshazzar ignored. Its heaven-sent light was meant to lead to reform, and neglecting and failing to practice such lessons brings judgment, with Babylon's coming calamity resulting from disregarding it.
