Jamieson, Fausset and Brown on 2 Kings 25:6-7

6-7. they took the king, and brought him ... to Riblah--Nebuchadnezzar, having gone from the siege to oppose the auxiliary forces of Pharaoh-hophra, left his generals to carry on the blockade, he himself not returning to the scene of action, but taking up his station at Riblah in the land of Hamath (2Ki 23:33).

they gave judgment upon him--They, that is, the council (Jr 39:3, 13; Da 6:7, 8, 12), regarding him as a seditious and rebellious vassal, condemned him for violating his oath and neglecting the announcement of the divine will as made known to him by Jeremiah (compare Jr 32:5; 34:2; 38:17). His sons and the nobles who had joined in his flight were slain before his eyes (Jr 39:6; 52:10). In conformity with Eastern ideas, which consider a blind man incapable of ruling, his eyes were put out, and being put in chains, he was carried to perpetual imprisonment in Babylon (Jr 52:11), which, though he came to it, as Ezekiel had foretold, he did not see (Jr 32:5; Eze 12:13; 17:16).
