12. (a) What change from his usual way of introducing references to the Hebrew Scriptures did Jesus make in his Sermon on the Mount, and why? (b) What do we learn from the sixth use of the expression “It was said”?

¹² When Jesus previously quoted from the Hebrew Scriptures, he said: “It is written.” (Matthew 4:4, 7, 10) But six times in the Sermon on the Mount, he introduced what sounded like statements from the Hebrew Scriptures with the words: “It was said.” (Matthew 5:21, 27, 31, 33, 38, 43) Why? Because he was referring to the Scriptures as interpreted in the light of Pharisaic traditions that contradicted God’s commandments. (Deuteronomy 4:2; Matthew 15:3) This is made apparent in Jesus’ sixth and last reference in this series: “You heard that it was said, ‘You must love your neighbor and hate your enemy.’” But no Mosaic law said, “Hate your enemy.” The scribes and Pharisees said it. That was their interpretation of the Law to love your neighbor​—your Jewish neighbor, no others.

14. How does Jesus counsel us not even to start down the road that leads to adultery?

¹⁴ Jesus next said: “You heard that it was said, ‘You must not commit adultery.’ But I say to you that everyone that keeps on looking at a woman so as to have a passion for her has already committed adultery with her in his heart.” (Matthew 5:27, 28) You are not going to commit adultery? Then do not even start down that road by entertaining thoughts about it. Guard your heart, where such things have their source. (Proverbs 4:23; Matthew 15:18, 19) James 1:14, 15 warns: “Each one is tried by being drawn out and enticed by his own desire. Then the desire, when it has become fertile, gives birth to sin; in turn, sin, when it has been accomplished, brings forth death.” People sometimes say: ‘Don’t start what you can’t finish.’ But in this case we should say: ‘Don’t start what you can’t stop.’ Some who have been faithful even when threatened with death before a firing squad have later fallen for the insidious lure of sexual immorality.
