קוֹל־יְהוָ֥ה בַּכֹּ֑חַ ק֥וֹל יְ֝הוָ֗ה בֶּהָדָֽר׃
여호와의 소리가 힘 있음이여 여호와의 소리가 위엄차도다
Rashi on Psalms
The voice of the Lord is in strength At the time of the giving of the Torah, He moderated His voice according to the strength of Israel, as it is said (Exod. 19:19): “and God would answer him with a voice,” with Moses’ voice.
