"If you walk in My statutes" (26:3). Or Daniel(
In the book "Otzar Hamidrashim" it is told of Rav Kahane who was counted as a son after many years. When the boy was three years old, Rav Kahane said to his wife: "The child must be taken to a teacher ." The woman said, "I can't do without him... Bring the teacher to us. He'll get a room here and I'll cook for him, and he'll eat and sleep here."
Rabbi Kahane went and found Rabbi Eliezer Zeira in the markets of Tiberias, about whom it is said that he wore black because he mourned for Jerusalem. His friends wanted to ostracize him on the grounds that it was pride, but after they saw that he was a Torah scholar, they left him alone. Rabbi Eliezer sat down and made tzitzit. Rav Kahane asked him, "Do you have a wife and children?" He answered, "Yes." Where are they?" My wife is the Torah and the children are the mitzvot." Rabbi Eliezer answered. Rav Kahane saw that this was the case and brought him to teach his son. He taught him for twenty-eight years, came to Rav Kahane and said to him, "I taught your son the entire Torah. I've finished my job."
The son went out to the market of Tiberias and was amazed by what they saw, approached a farm seller and asked for a glass of water. The seller answered, "Please, but pay first ." The son said, "But I don't have any money!" "If there is no money, there is no water!" answered the seller. The son said to him, "I am the son of Rav Kahane!" The seller answered, "And I am the grandson of Yaakov our father... You only get water for money." The son thought and said, "I know the entire Torah!" The salesman answered, "Great, but to drink you have to pay!"
The son came home and said that he was going out to "make money" because that's what people value. His father gave him a large diamond and told him, "Go to the market tomorrow, and since you don't know much about trading, go around the market and ask about the prices that will be offered to you. Don't sell the diamond yet. In the evening tell me about the offers, and then we will decide who to sell to." The son went out to the market and came to the cobblers' street, asked them, "How much do you offer for the diamond?" The cobblers saw the diamond and admired its size and offered a hundred gold coins. From there he went on to the market of the Killers and offered it to them. The Killers looked at them and said, "We will pay you a thousand gold coins for him!" At the cooks' market, they offered him five thousand gold coins in exchange for the diamond. At the end of the day, he arrived at the diamond market. The diamond dealers had never seen such a large stone in their lives and immediately offered him a million gold coins! He returned home in the evening and told his father about his tour and its results. His father said to him, "I don't understand! After all, they offered a variety of prices, who is really right, the shoemakers or the diamond dealers? "And why did the cobbler market offer you only a hundred?" The son answered, "Very simple, they don't understand beautiful stones. In order to know the true value of the stone, you have to go to a place where you understand stones, only in the diamond market." Rav Kahane said to him: "Let your ears hear what your mouth speaks. You have to go to someone who understands the merchandise in question, and hear from him how much he appreciates it. You went out to the market and walked around people who were busy all day "making money" and you heard from them that they don't appreciate the entire Torah, because they don't understand the Torah. Tomorrow you will go out with me to a meeting where they know how to appreciate this commodity and then you will see how much it is worth in their eyes."
