They have wandered as blind men in the streets - Rather, "They ran frantic through the streets, they were stained with blood." This was in their pretended zeal for their cause. Bishop Bonner, who was at the head of those sanguinary executions in England, was accustomed to buffet the poor Protestants, when on their examinations they were too powerful for him in argument: -
"He proved his doctrine orthodox,
By apostolic blows and knocks."
Just as his elder brethren, the false priests and prophets of Jerusalem.
They have wandered - God‘s ministers, consecrated to His service, wandered through the city blinded by the insatiable lust of slaughter. It was a pollution to touch their garments.
