Isaiah 14:6

“He who smote the people in wrath with a continual stroke, &c.] The king of Babylon, who made war with the people and nations of the earth, and conquered them, smote them with the edge of the sword to gratify his passions, and satiate his bloodthirsty mind; and those that were spared, he ruled with rigour, and oppressed them with tribute and hard bondage; and, when he had conquered one nation, attacked another, and so went on pursuing his victories without intermission, giving no respite neither to his army, nor to the people: he that ruled the nations in anger; not with justice and clemency, but in a tyrannical and oppressive way, even his own nation, as well as the nations whom he subdued:…”

With a continual stroke - Margin, ‘A stroke without removing.’ Vulgate, Plaga insanabili - ‘With an incurable plague.’ - Septuagint the same - Πληγῇ ἀνιάτῳ Plēgē aniatō. The Hebrew is, as in the margin, ‘A smiting without removing,’ or without cessation. There was no relaxation in its oppressions, it was always engaged in acts of tyranny. He that ruled the nations…”

“Anger - With rigour and not with clemency. None - Neither the Babylonians themselves, nor their confederates. Isaiah 14:7”
