פירוש על קידושין 66:3

R. Elazar reads a verse in Kohelet in light of the verse about standing before a sage in Leviticus. Both contain the phrase “fear God” and while other verses talk about fearing God in the context of other mitzvoth (not having false weights, and not lending to other Jews with interest) only these two verses use the word “pene.” The verse about rising reads “מפני שיבה” and the verse in Kohelet says, “מלפני אלוהים.”
R. Elazar derives that he will forget his Talmud from the phrase “Good (tov) will not be”—“good” is a code word for Torah, as in the phrase, “For I have given you a good teaching.”
