Musar su Deuteronomio 32:26

The apostate explained, “I once heard in one of your sermons that all the commandments are contained in Parashas Ha’azinu and that all the events of history are hinted there as well. However, one requires the help of Heaven to understand all those allusions and secrets.” Since the disciple considered all this to be impossible he became persuaded that what the Ramban was saying was not true, whereupon he went out and cast off the yoke of Torah and became a different person. The Ramban replied, “I still insist that what I said was correct. Everything is hinted at clearly in Parashas Ha’azinu. If you do not believe me, ask me for an example and I will answer you.” The apostate was taken aback and said, “If what you say is true, show me where my name, Avner, is alluded to there!” So the Ramban prayed with all his heart and soul until there came to him the verse: “I said I would scatter them to the corners, I would make the remembrance of them to cease from among men” (Devarim 32:26). In this verse taking the third letter of each word spells out the name “R. Avner,” as follows: Amarti (אמרתי) afeihem (אפאיהם) asbisah (אשביתה) mei’enosh (מאנוש) zichram (זכרם).
