הֵן־אֱ֭מֶת חָפַ֣צְתָּ בַטֻּח֑וֹת וּ֝בְסָתֻ֗ם חָכְמָ֥ה תוֹדִיעֵֽנִי׃
看哪，你喜愛人在內心深處存著真實；你也在我隱密的心中使我明白智慧。
Rashi
Behold, You desired that truth be in the hidden places and behold, I confess to the truth, that I sinned.
Rashi
in the hidden places Heb. בטחות. These are the reins, which are smooth. Menachem (p. 97), however, associated it with (Gen. 21:16): “as it were a bowshot (כמטחוי קשת)”; and so (Job 38: 36): “Who placed wisdom in the inward parts (בטחות).” And their interpretation is an expression of drawing, for just as a bow is drawn, so is their yearning for knowledge.
Rashi
and in the concealed part You teach me wisdom And in the heart, which is concealed, You have taught me wisdom to confess.
