Charles Ellicott Commentary 2 Kings 25:6

"Then they took the king, and carried him up unto the king of Babylon to Riblah; and they gave judgment upon him." — 2 Kings 25:6 (ASV)

To the king of Babylon, to Riblah (2 Kings 23:33). Nebuchadnezzar was not present at the storm of Jerusalem (Jeremiah 39:3). He awaited the result in his headquarters.

And they gave judgment upon him. Or, brought him to trial. (Jeremiah 4:12). Nebuchadnezzar, with the grandees of his court, perhaps including some dependent princes of the country, held a solemn trial of Zedekiah as a rebel against his overlord, in which, no doubt, his breach of oath was made prominent (2 Chronicles 36:13; Ezekiel 17:15; Ezekiel 17:18). The verb is singular in Jeremiah and the versions. (See next Note.)
