'Sin' in the Bible

To take that position as a servant and Apostle, from which Judas by his sin was shut out, so that he might go to his place.

And he kneeled down, and cried with a loud voice, Lord, lay not this sin to their charge. And when he had said this, he fell asleep.

For I see that you are bitterly envious and in bondage to sin."

he making defence -- 'Neither in regard to the law of the Jews, nor in regard to the temple, nor in regard to Caesar -- did I commit any sin.'
