John Calvin Commentary Ezekiel 19:9

"And they put him in a cage with hooks, and brought him to the king of Babylon; they brought him into strongholds, that his voice should no more be heard upon the mountains of Israel." — Ezekiel 19:9 (ASV)

He pursues the same subject, saying that King Jehoiakim, after being taken captive, was bound with fetters and chains, adding that he was brought to the king of Babylon, and thirdly, was cast into prison.

He shows, therefore, how severely God punished the vicious obstinacy of that nation: for when King Jehoiakim was chastised, it was thought that this would be enough to correct them at that time; but since the people were not improved by this, the severity was doubled; and here Ezekiel says, that King Jehoiakim was cast into a fortified dungeon. He adds, that his voice, that is, his roaring, should be no longer heard in the mountains of Israel.

For although he was reduced to straits, since a great part of his kingdom had been cut off, yet he did not desist from his ferocity. The Prophet, therefore, sharply derides his insolence, since he did not cease to cry out and to roar even in the mountains of Israel.
