יְהוִ֤הּ אֲדֹנָי֙ חֵילִ֔י וַיָּ֤שֶׂם רַגְלַי֙ כָּֽאַיָּל֔וֹת וְעַ֥ל בָּמוֹתַ֖י יַדְרִכֵ֑נִי לַמְנַצֵּ֖חַ בִּנְגִינוֹתָֽי׃
Yang Mahakekal, Tuhan, adalah kekuatanku; Ia membuat kakiku seperti kaki rusa betina, dan di tempat-tempatku yang tinggi Ia membuat aku melangkah. Untuk pemimpin nyanyian, dengan iringan alat-alat musikku.
