פִּ֭י יְדַבֵּ֣ר חָכְמ֑וֹת וְהָג֖וּת לִבִּ֣י תְבוּנֽוֹת׃
Mulutku akan mengucapkan hikmat, dan renungan hatiku adalah pengertian.
Rashi
and the thoughts of my heart are understanding The thoughts of my heart are understanding.
Ibn Ezra
"My mouth" - to teach all the wisdom hidden from them, which those wise of heart explain by riddles.
