Dost not thou fear God ... - You are condemned to die as well as he. It is improper for you to rail on him as the rulers and Romans do. God is just, and you are hastening to his bar, and you should, therefore, fear him, and fear that he will punish you for railing on this innocent man.
Same condemnation - Condemnation to death; not death for the same thing, but the same “kind” of death.
