A.T. Robertson Commentary Luke 23:19

"one who for a certain insurrection made in the city, and for murder, was cast into prison." — Luke 23:19 (ASV)

Insurrection (στασιν). An old word for sedition, standing off, the very charge made against Jesus (and untrue). If Jesus had raised insurrection against Caesar, these accusers would have rallied to his standard.

And for murder (κα φονον). They cared nought for this. In fact, the murderer was counted a hero like bandits and gangsters today with some sentimentalists.

Was cast (ην βληθεις). Periphrastic aorist passive indicative of βαλλω, a quite unusual form.
