לֵ֣ב טָ֭הוֹר בְּרָא־לִ֣י אֱלֹהִ֑ים וְר֥וּחַ נָ֝כ֗וֹן חַדֵּ֥שׁ בְּקִרְבִּֽי׃
하나님이여 내 속에 정한 마음을 창조하시고 내 안에 정직한 영을 새롭게 하소서
Zohar
Thus it is written, "and let birds fly above the earth," because the Torah that is called "the waters" (Genesis 1:20) abounds, bringing forth expressions of the living soul, that is aroused from its place of living creature, to be drawn down below, as we have learned. And this is what King David referred to, when he said, "Create in me a clean heart, O Elohim" (to study and learn the Torah), and then "renew a steadfast spirit within me" (Psalms 51:12).
