Kabbalah zu Schemot 25:18

And who sustains the world, and causes the Patriarchs to appear? It is the voice of the children, who study the Torah. It is the voice of the children, who study the Torah. And since they grow in the world, the world is sustained. In deference to them, it is written, "We will make you necklets of gold" (Songs 1:11). This refers to the children that grow strong in the world, as is written, "And you shall make two Cherubs of gold" (Exodus 25:18).
