Jasidut sobre I Reyes 3:9

And this is the explanation [of] (Ps. 103): "Mighty [men] of strength who perform His word, hearing the voice of His word;" it is brought in the Zohar (Lekh daf 90): "They are fortunate to hear report of voices from on high" i.e. via the gevurot/strengths are made thunders, and via this the heart hears, and i.e. "וְהָגוּת לִבִּי תְּבוּנוֹת/and the contemplation of my heart shall be understanding;" and as written (I Kings 3): "Give Your servant a hearing heart;" and his words will also be listened to by creatures, and this is: "...hearing the voice of His word,"

This is the meaning of “should apprentice to Shimon ben (son of) Nanas.” For hearing is dependent upon the lev (heart). This is because ChaShMaL LeV has the same numerical value as SheMA (hear), [and] as is written (1 Kings 3:9), “Give, then, Your servant a hearing heart.” <that is,="" “should="" apprentice="" to="" shimon”—he="" should="" draw="" chashmal="" from="" lev,="" which="" is="" an="" aspect="" of="" shema="" —to="" “ben="" nanas”—i.e.,="" to="" faith,="" which="" is="" an="" aspect="" of="" ban="" and="" nanas,=""> the small light.
