How great is the preservation of peace, for even the Holy One Blessed Is He altered the truth for the sake of peace! For initially it is written that Sarah laughed to herself at the absurdity of having a child, saying: “My husband is old!” Yet later, when God related her statement to Avraham, it is written: “Why did Sarah laugh, saying: ‘Shall I indeed bear a child, though I am old?’” ~ Talmud Yevamot 65b
