Prepare a place to slaughter his sons for the iniquities of their forefathers. They will never rise up to possess a land or cover the earth with their cities.
21. Prepare slaughter for his children. Here Isaiah prophesies more plainly than before against the king of Babylon. He speaks of the whole of his descendants, to whom he intimates that this destruction extends. We must keep in mind what we formerly said, that hitherto the Prophet has spoken not of a single man, but of a whole dynasty; and now he removes all doubt as to the metaphorical language.
The kings of Babylon, successively, were the great enemies and oppressors of God's people, and therefore the destruction of Babylon, the fall of the king, and the ruin of his family, are here particularly taken notice of and triumphed in. In the day that God has given Israel rest they shall take up this proverb against the king of Babylon.
Commenting on Isaiah 14:4-23
Prepare slaughter for his children,.... These words are directed to the Medes and Persians, to prepare instruments of slaughter, and make use of them; and prepare themselves for the slaughter of the whole royal family, Belshazzar and all his children.
