רֽוֹמְמ֡וּ יְה֘וָ֤ה אֱלֹהֵ֗ינוּ וְ֭הִֽשְׁתַּחֲווּ לְהַ֣ר קָדְשׁ֑וֹ כִּֽי־קָ֝ד֗וֹשׁ יְהוָ֥ה אֱלֹהֵֽינוּ׃
Rashi on Psalms
for the Lord our God is holy because He is strict with the righteous, He is sanctified in the world, and so He says (Exod. 29:43): “and it will be sanctified with My glory,” meaning “with those glorified by Me.”
