Kabbalah su I Samuele 25:78

Rabbi Abba opened the discussion saying, "And thus (Heb. כֹּה) shall you say so to him, a hearty greeting (lit. 'to the living')! Peace be both to you, and peace to your house, and peace to all that you have" (I Shmuel 25:6). "And you shall say koh to the living,". Did not David know Naval to be evil, to have said of him, "כֹּה to the living?" That day was the holy day of Rosh Hashanah (the New Year) and the Holy One, blessed be He, was sitting in judgment over the world. For the Holy One, blessed be He, said, "And you shall say כֹּה to the living" in order to attach 'כֹּה' to the 'living', from which all life comes. "Peace be both to you." What is "both to you?" "Both to you" refers to the Holy One, blessed be He, in order to connect the link of Faith, as is proper.
