The Jews are created to find everything ready. The rabbi continues his examination. Honor is the surest defense. They mean that one should always be honest in life. One should not lie and cheat.
All lies are good.
To cheat a Gentile is permitted. When we loan the Gentiles money, we must demand usurious interest. The Gentile may not rob the Jews. But the Jews may at any time rob the Gentiles. The Jewish court will stand by the Jew.
