{To councils} (eis sunedria). The local courts of justice in
every Jewish town. The word is an old one from Herodotus on for
any deliberative body (concilium). The same word is used for
the Sanhedrin in Jerusalem. {In their synagogues} (en tois
sunag(9367)ais aut(936e)). Here not merely as the place of assembly for
worship, but as an assembly of justice exercising discipline as
when the man born blind was cast out of the synagogue ( Joh
9:35 ). They were now after the exile in every town of any size
where Jews were.
