Midrasz do Izajasza 65:8
כֹּ֣ה ׀ אָמַ֣ר יְהוָ֗ה כַּאֲשֶׁ֨ר יִמָּצֵ֤א הַתִּירוֹשׁ֙ בָּֽאֶשְׁכּ֔וֹל וְאָמַר֙ אַל־תַּשְׁחִיתֵ֔הוּ כִּ֥י בְרָכָ֖ה בּ֑וֹ כֵּ֤ן אֶֽעֱשֶׂה֙ לְמַ֣עַן עֲבָדַ֔י לְבִלְתִּ֖י הַֽשְׁחִ֥ית הַכֹּֽל׃
Tak rzecze Wiekuisty: Jak gdy się znajduje moszcz w gronie, a powiadają: nie psuj go, bo błogosławieństwo w niém! tak uczynię gwoli sługom Moim, że nie wygubię ich wszystkich.
Bereishit Rabbah
Rabbi Simon began: "Thus said Hashem: As, when new wine is present in the cluster, One says, “Don’t destroy it; there’s good in it,” So will I do for the sake of My servants, And not destroy everything (Isaiah 65:8)". A certain pious man went out from his vineyard on Shabbat and saw one cluster of grapes and said a blessing upon it. He said: "This cluster is deserving", and so he was blessed by it. Thus is said: ""Thus said Hashem: As, when new wine is present in the cluster".
