יְר֣אוּ אֶת־יְהוָ֣ה קְדֹשָׁ֑יו כִּי־אֵ֥ין מַ֝חְס֗וֹר לִירֵאָֽיו׃
פֿאָרכט גאָט, איר זײַנע הײליקע, װאָרום זײַנע פֿאָרכטער װעט ניט פֿעלן.

And this is the inner awe/respect, about which I explained in the Gate of Awe/Respect, second chapter, which is to respect God’s greatness. And this respect can only be developed through holiness, as it is written “Have Ad-nai in awe, you His consecrated ones” (Psalms 34:10), since if one simply follows the lusts of the world, one has no respect at all.
