כִּֽי־יְ֭הוָה יִהְיֶ֣ה בְכִסְלֶ֑ךָ וְשָׁמַ֖ר רַגְלְךָ֣ מִלָּֽכֶד׃
Sapagkat ang Walang-Hanggan ang magiging iyong pag-asa, at iingatan Niya ang iyong paa upang hindi ito mahuli sa bitag.
Rashi
For the Lord shall be your trust Heb. בכסלך, in your trust. Another explanation: in the things concerning which you are a fool (כסיל). This I found in Yerushalmi.
