Kabbalah su Giobbe 28:21

"She opened her mouth with wisdom"because it is concealed and utterly unrevealed, as it is written, "Seeing it is hidden from the eyes of all living, and kept close from the birds of the sky" (Iyov 28:21). When (Binah) started to spread together with Chochmah that cleaved to it and was clothed in it, it issued a sound, which is "a Torah of Chesed."
