4:19-27 Daniel was struck with amazement and terror at so heavy a judgment coming upon so great a prince, and gives advice with tenderness and respect. It is necessary, in repentance, that we not only cease to do evil, but learn to do good. Though it might not wholly prevent the judgment, yet the trouble may be longer before it comes, or shorter when it does come. And everlasting misery will be escaped by all who repent and turn to God.
19. Daniel … Belteshazzar—The use of the Hebrew as well as the Chaldee name, so far from being an objection, as some have made it, is an undesigned mark of genuineness. In a proclamation to "all people," and one designed to honor the God of the Hebrews, Nebuchadnezzar would naturally use the Hebrew name (derived from El, "God," the name by which the prophet was best known among his countrymen), as well as the Gentile name by which he was known in the Chaldean empire.
astonied—overwhelmed with awe at the terrible import of the dream.
one hour—the original means often "a moment," or "short time," as in Da 3:6, 15.
let not the dream … trouble thee—Many despots would have punished a prophet who dared to foretell his overthrow. Nebuchadnezzar assures Daniel he may freely speak out.
the dream be to them that hate thee—We are to desire the prosperity of those under whose authority God's providence has placed us (Jer 29:7). The wish here is not so much against others, as for the king: a common formula (2Sa 18:32). It is not the language of uncharitable hatred.
