Hang all the Law and the prophets; i.e. all Scripture, which is comprised in these terms (comp. Matthew 5:17; Matthew 7:12); in other words, all the revelations which God has made to man in every age.
The clause is peculiar to St. Matthew. It signifies that on love of God and love of man depend all the moral and religious, ceremonial and judicial precepts contained in the Law, all the utterances of the prophets, all the voices of history.
Scripture enunciates the duty to God and our neighbour, shows the right method of fulfilling it, warns against the breach of it, gives examples of punishment and reward consequent upon the way in which the obligation has been treated.
Thus the unity and integrity of revelation is demonstrated. Its Author is one; its design is uniform; it teaches one path, leading to one great end.
