וְיָדַ֣עְתִּי אֱלֹהַ֔י כִּ֤י אַתָּה֙ בֹּחֵ֣ן לֵבָ֔ב וּמֵישָׁרִ֖ים תִּרְצֶ֑ה אֲנִ֗י בְּיֹ֤שֶׁר לְבָבִי֙ הִתְנַדַּ֣בְתִּי כָל־אֵ֔לֶּה וְעַתָּ֗ה עַמְּךָ֙ הַנִּמְצְאוּ־פֹ֔ה רָאִ֥יתִי בְשִׂמְחָ֖ה לְהִֽתְנַדֶּב־לָֽךְ׃
At nalalaman ko, aking Diyos, na Ikaw ang sumisiyasat sa puso, at kinalulugdan Mo ang katapatan. Ako, sa katapatan ng aking puso, ay kusang-loob na naghandog ng lahat ng ito; at ngayon ay nakita ko ang Iyong bayan na naririto na kusang-loob na naghahandog sa Iyo nang may kagalakan.
