'Subject' in the Bible

"You have heard that it was said to the {people of old}, 'Do not commit murder,' and 'whoever commits murder will be subject to judgment.'

But I say to you that everyone who is angry at his brother will be subject to judgment, and whoever says to his brother, 'Stupid fool!' will be subject to the council, and whoever says, 'Obstinate fool!' will be subject to fiery hell.
