24 But we would not hearken unto thy voice, to serve the king of Babylon: therefore hast thou made good the words that thou spakest by thy servants the prophets, namely, that the bones of our kings, and the bones of our fathers, should be taken out of their place.
[AD 458] Theodoret of Cyrus on Baruch 2:24
And not only have we who are alive been given over to servitude, but also the tombs of our ancestors, in particular those of the kings, were destroyed to their foundations, and their bones were scattered and exposed to the open air to be corroded by the elements.

[AD 600] Olympiodorus of Alexandria on Baruch 2:24
After death, their bones were to suffer as a sign of the future judgment.
