Matthew 22:36

ποία ἐντολὴ : what sort of a commandment? it is a question not about an individual commandment, but about the qualities that determine greatness in the legal region. This was a question of the schools. The distinction between little and great was recognised (vide chap. Matthew 5:19), and the grounds of the distinction debated (vide Schöttgen, ad loc., who goes into the matter at length). Jesus had already made a contribution to the discussion by setting the ethical above the ritual (Matthew 15:1-20, cf. Matthew 19:18-22).
