John Calvin on Ezekiel 19:6

Ezekiel confirms what I have already briefly touched on, that this second lion was no less savage and cruel than the former, of which he had spoken. As to the phrase, he walked among lions, it means that his government was tyrannical, since there was then such foul barbarity in those regions, that, kings were scarcely human in their conduct. Since, therefore, kings were then everywhere like lions, the Prophet says that Jehoiakim was not different from them, but in every sense their ally. He walked, therefore, he says, in the midst of lions, since he imitated their ferocity, which at length he expresses more clearly, that he became a lion, and was taught to seize his prey, so as to devour not only animals, but men, thus marking his extreme cruelty. He afterwards adds —

Ezekiel 19:7

7. And he knew their desolate palaces, and he laid waste their cities; and the land was desolate, and the fulness thereof, by the noise of his roaring.

7. Et contrivit, Or, “afflicted.” — Calvin. palatia ejus, et urbes eorum destruxit, et redacta fuit in solitudinem terra, et plenitudo ejus a voce rugitus illius.
