John Calvin on Matthew 23:32

32. Do you then fill up the measure of your fathers. He at length concludes that they are not, in this respect, degenerate from their fathers; as if he had said, “It is not now that your nation begins to treat with cruelty the prophets of God; for this is the ancient discipline, this is the custom handed down from the fathers, and, in short, this way of acting is almost natural to you.” And yet he does not bid them do what they are doing, to put to death holy teachers, but states figuratively that they have a hereditary right to rise against the servants of God, and that they must be permitted to oppose religion, because in this way they fill up what is wanting in the crimes of their fathers, and finish the web which they had begun. By these words he not only pronounces themselves to be desperate, and incapable of being brought to a sound mind, but warns simple people that there is no reason to wonder, if the prophets of God are ill-treated by the children of murderers.
