And as they went about to kill him, tidings came unto the chief captain of the band, that all Jerusalem was in an uproar.
And as they went about ('sought') to kill him, tidings came, [anebee (G305 )] - 'came up,' a graphic allusion to the elevated position of the castle, which was built by Herod the Great on a high rock at the northwest corner of the great temple area, and called, after Mark Antony, the castle or fortress of Antonia.
Unto the chief captain of the band, [too (G3588) chiliarchoo (G5506) tees (G3588) speiras ( G4687)] - properly, 'the prefect' or 'tribune of the cohort;' the commander of the garrison quartered in the castle, Claudius Lysias (Acts 23:26). The full number of the cohort was 1000 men: Josephus informs us (Jewish Wars, 5: 5, 8) that the garrison were ordered to remain under arms during the festivals in case of any outbreak.
That all Jerusalem was in an uproar. This part of the narrative is particularly graphic.
