Gen 18:28

א֠וּלַי יַחְסְר֞וּן חֲמִשִּׁ֤ים הַצַּדִּיקִם֙ חֲמִשָּׁ֔ה הֲתַשְׁחִ֥ית בַּחֲמִשָּׁ֖ה אֶת־כָּל־הָעִ֑יר וַיֹּ֨אמֶר֙ לֹ֣א אַשְׁחִ֔ית אִם־אֶמְצָ֣א שָׁ֔ם אַרְבָּעִ֖ים וַחֲמִשָּֽׁה׃

suppose the fifty righteous ones lack five. Will You destroy the whole city for the lack of five?” He replied, “If I find forty-five there, I will not destroy it.”
