By the time of Jesus, 613 commandments had grown up surrounding the official biblical law. While all were considered delivered by God to Moses, some were more important than others. The scribe should have understood this. Jesus does not single out any particular law, but endorses the summons that constitutes the Shema, the most significant prayer of the Israelite religion (cf, Deut 6:5). Jesus was asked to identify one commandment, and he offers two. The second is a citation from the Book of Leviticus (19:18). By bringing these admonitions together as he does, Jesus shows that, though not identical, they are interrelated. No one dared challenge Jesus again. What else was there to ask? What other answer could be given?
