כִּֽי־תֹאמַ֗ר הֵן֮ לֹא־יָדַ֪עְנ֫וּ זֶ֥ה הֲֽלֹא־תֹ֘כֵ֤ן לִבּ֨וֹת ׀ הֽוּא־יָבִ֗ין וְנֹצֵ֣ר נַ֭פְשְׁךָ ה֣וּא יֵדָ֑ע וְהֵשִׁ֖יב לְאָדָ֣ם כְּפָעֳלֽוֹ׃
你若說：«看哪，這事我們並不知道。»那鑒察人心的豈不明白嗎？那保守你性命的豈不知道嗎？他必按各人的行為報應人。
Duties of the Heart
(2) To know and clearly realize that the Creator is watching him, and neither one's private or public conduct is hidden from Him, nor his innermost being or outer appearance. He also knows whether a man's trust in Him is with a sincere heart or not, as the verse says "G-d knows the thoughts of the heart, that they are vain" (Tehilim 94:11) and "Does not He that tests the heart understand it?" (Mishlei 24:12), and "You alone know the hearts of all men" (Melachim I 8:39).
