Exodus 29:39שמות כ״ט:ל״ט
You shall offer the one lamb in the morning, and you shall offer the other lamb at twilight.
Megillah 28a:10מגילה כ״ח א:י׳
On a similar occasion, Rabbi Akiva asked Rabbi Neḥunya the Great; he said to him: In the merit of which virtue were you blessed with longevity? Rabbi Neḥunya’s attendants [gavzei] came and started beating Rabbi Akiva, for they felt that he was acting disrespectfully by highlighting Rabbi Neḥunya’s old age. Rabbi Akiva ran away from them, and he climbed up and sat upon the top of a date palm. From there, he said to Rabbi Neḥunya: My teacher, I have a question about the verse concerning the daily offering that states “one lamb” (Numbers 28:4). If it is stated “lamb” in the singular, why is it also stated “one”; isn’t this superfluous? Upon hearing Rabbi Akiva’s scholarly question, Rabbi Neḥunya said to his attendants: He is clearly a young Torah scholar, let him be.
