The moment that Nebuchadnezzar appears is the moment that Jehoiachin surrenders, along with his mother (see 2 Kings 24:12) and his household. The dating is from Babylonian historiography: Jehoiachin was captured in the eighth year of Nebuchadnezzar’s reign. The author of Kings clearly knows the Babylonian historiography.
12 Alors Jojakin, roi de Juda, se rendit auprès du roi de Babylone, avec sa mère, ses serviteurs, ses chefs et ses eunuques. Et le roi de Babylone le fit prisonnier, la huitième année de son règne.
