John Calvin on Isaiah 5:3

3. Now, therefore, O inhabitant of Jerusalem! Those persons with whom he contends are made judges in their own cause, as is usually done in cases so plain and undoubted that the opposite party has no means of evasion. It is, therefore, a proof of the strongest confidence in his cause, when he bids the guilty persons themselves declare if this be not the true state of the fact; for immediately afterwards we shall find him declaring that the accusation is decided against those persons to whom he now commits the decision.
