Tractate Pirkei Avot - Chapter 6 - Mishnah 9

Rabbi Yose ben Kisma said: Once I was walking by the way when a man met me, and greeted me and I greeted him. He said to me, “Rabbi, where are you from?” I said to him, “I am from a great city of sages and scribes”. He said to me, “Rabbi, would you consider living with us in our place? I would give you a thousand thousand denarii of gold, and precious stones and pearls.” I said to him: “My son, even if you were to give me all the silver and gold, precious stones and pearls that are in the world, I would not dwell anywhere except in a place of Torah; for when a man passes away there accompany him neither gold nor silver, nor precious stones nor pearls, but Torah and good deeds alone, as it is said, “When you walk it will lead you. When you lie down it will watch over you; and when you are awake it will talk with you” (Proverbs 6:22). “When you walk it will lead you” in this world. “When you lie down it will watch over you” in the grave; “And when you are awake it will talk with you” in the world to come. And thus it is written in the book of Psalms by David, king of Israel, “I prefer the teaching You proclaimed to thousands of pieces of gold and silver” (Psalms 119:72), And it says: “Mine is the silver, and mine the gold, says the Lord of Hosts” (Haggai 2:8).
