"Three years before, the rulers of the temple had been ashamed of their flight before the command of Jesus. They had since wondered at their own fears, and their unquestioning obedience to a single humble Man. They had felt that it was impossible for their undignified surrender to be repeated. Yet they were now more terrified than before, and in greater haste to obey His command. There were none who dared question His authority. Priests and traders fled from His presence, driving their cattle before them. DA 591.1"
