GEN952 In certain situations the Sages allowed an altering of the truth … For example, it is permitted, and indeed a mitzvah, to alter the truth to bring peace between two parties in a dispute, or between quarreling spouses. We find that even Hashem altered the truth in order to bring peace into a marriage. Rashi, Bereishis 18:13, and Talmud, Yevamos 65b.  The Sages also encourage us to follow the example of Aharon. When Aharon the Kohen would see that two people were fighting he would go to one sit with him, and say, “Your friend feels so bad, he is so embarrassed because he feels he is at fault …,” and would stay with him until his feelings of animosity would completely dissipate. Then Aharon would go to the antagonist and sit with him and say, “Your friend feels so bad, he is so embarrassed because he feels his is at fault…,” and would stay with him until his animosity would completely dissipate. Then the two would meet on the street and they would embrace. Pirkei Avos 1;12, Avos D’Rabbi Nosson 12:3 JOURNEY 94-5
