I Samuel 25:37 Kabbalah

וַיְהִ֣י בַבֹּ֗קֶר בְּצֵ֤את הַיַּ֙יִן֙ מִנָּבָ֔ל וַתַּגֶּד־ל֣וֹ אִשְׁתּ֔וֹ אֶת־הַדְּבָרִ֖ים הָאֵ֑לֶּה וַיָּ֤מָת לִבּוֹ֙ בְּקִרְבּ֔וֹ וְה֖וּא הָיָ֥ה לְאָֽבֶן׃

And it came to pass in the morning, when the wine was gone out of Nabal, that his wife told him these things, and his heart died within him, and he became as a stone.
