Хасидус к Тегилим 49:4

פִּ֭י יְדַבֵּ֣ר חָכְמ֑וֹת וְהָג֖וּת לִבִּ֣י תְבוּנֽוֹת׃

Мой рот будет говорить мудрость, и медитация моего сердца будет понимание.

Likutei Moharan

And when it hits the rainclouds, then the voice is heard לְבִריָּתָא/by creatures, i.e. aspect of thunders, and this is [Ps. 77] "קוֹל רַעַמְךָ בַּגַּלְגַּל/the voice of Your thunder is in the galgal/spheroid" i.e. in the skull of the brain; when it encounters the skull of the brain from the voice are produced thunders, and it is heard by Creation.
