אזל לגביה א"ל ממנו לא שמעתי אלא כך אמר לי שמואל בר נחום אחי אמו של רב אחא ברבי חנינא ואמרי לה אבי אמו של רב אחי ברבי חנינא הואיל וסופן להשתבר
Go therefore to R. Tanhum b. Hanilai who was intimate with R. Joshua b. Levi, who was an expert in <i>Aggadah</i>. When he came to him he was told by him thus: 'From R. Joshua b. Levi I have not heard anything on the matter. But R. Samuel b. Nahum the brother of the mother of R. Aha son of R. Hanina, or as others say the father of the mother of R. Aha son of R. Hanina, said to me this: Because the [first tablets containing the] Commandments were destined to be broken.'<span class="x" onmousemove="('comment',' Ex. XXXII, 19.
