וַֽיהוָ֖ה בְּהֵיכַ֣ל קָדְשׁ֑וֹ הַ֥ס מִפָּנָ֖יו כָּל־הָאָֽרֶץ׃ (פ)
但永恆者在祂的聖殿中;全地都當在祂面前肅靜無聲。
Tze'enah Ure'enah
“The Lord is in His Temple” [2:20]. The prophet said: the Holy One is high in heaven and the people on the earth must fear, because the Holy One sees all the people on the earth and all of their deeds from heaven. Therefore, each person should be afraid to do evil.1Radak, Habakkuk, 2:20.
Rashi
Silence the whole earth before Him הַס is an expression of silencing and the silence of destruction.
