Kabbalah su Cantico dei cantici 1:4

Rabbi Yochanan said that we should not contradict this belief, but support the idea, because the Torah bears witness to it (Lev. 26:5). We already know the Faith of the Righteous and their desire from the verses, "we will be glad and rejoice in You" (Shir Hashirim 1:4), and not in eating, and "we will praise your love more than wine" (Vayikra 26:5). That feast, that they are destined for, we will partake of it too. This is the part of joy and laughter. "And these are the generations of Isaac (lit. 'will laugh')," for the righteous will laugh in the future. "Abraham begot Isaac," as it is the virtue of the soul that begets that laughter and joy in the world.
