Référence sur Les Nombres 14:20

When God was angry at the sin of the spies, he relented after Moses’ prayer and said “I have forgiven according to your words”. (Numbers, 14:20.) The meaning of this is that when the Gentiles will hear of it they will say: “Happy is the pupil whose teacher agrees with his words.”¹⁹⁾ברכות ל״ב א׳.
