Тегилим 12:1 Мидраш: Midrash Tehillim & Sifrei Devarim

"May the conductor of the eighth be saved. Save us, O Lord, for we are godly; may the prophecy in Micah 7:2 be fulfilled. Andreas Shechik Tamia asked on what merit this nation stands. They said to him that it has pious men, righteous men, and men who toil in the Torah. Immediately he decreed and cast anger upon the land, so that they should not engage in Torah study. Therefore, David said, "Save us, O Lord, for we are godly." There was a story about a pious man who found a box full of coins that had been lost, and brought it to her. When they brought it to her, they said to her, "He does not know what it is, so he brought it to you." She said to them, "It is all gold, from one end to the other, and you say he does not know what it is?" They said to her, "He will return your loss to you." She cursed him, and they decreed that he should go in and out without permission. They found people engaged in that profession, and the same pious man turned them away. When he died, they recited over him, "Save us, O Lord, for we are godly," for faith had departed from men. Rabbi Pinchas said, "Men may fail, but the angels do not fail." And what were men engaged in? They spoke evil of one another. There was a story in a city that had no salt at all, and there was one group of donkeys. They said, "We will go and bring salt and sell it until others come." They had a leader, and they went to him and said, "We will go." He said to them, "I have to plow today and tomorrow, but wait for me until I plow, and the day after tomorrow we will go together." They said to him, "Yes." In the morning, what did he do? He said to his wife, "If I tell you, give me the yoke, give me the jug, give me the bag." What did he do? He put the bag on the donkey's back..." The neighbors told them that he had already left since last night. When they heard this, they went on their way and found him returning. They asked him why he did that. He said to them, "Don't you know that if we all went together, the price would have gone down? Now that I have brought some alone, by the time you come to me, it will be sold at a high price, and when you sell it, it will be beautiful." Therefore, it is said, "In vain do they talk to one another" (Jeremiah 9:7). There is a story about Rabbi Yonatan, who had lentils at an expensive price, and a relative of his came to him and asked him for lentils. Rabbi Yonatan said he had some, and told his relative the price, promising to sell it to him whenever he came. After a few days, Rabbi Yonatan went to his relative's house and asked his wife where he was. She told him that he was waiting for him in the field but he hadn't come back yet. Rabbi Yonatan asked someone if there were any lentils around, and the man told him there were none. Rabbi Yonatan then asked the man for lentils and agreed to pay the price that he had previously told his relative. When the relative arrived and complained to Rabbi Yonatan about the high price he had paid, Rabbi Yonatan said to him, "Perhaps you first asked for lentils?" The relative replied that he had. Rabbi Yonatan said, "If you had asked for wheat first, they would have said, 'Do you want lentils now?' But since you asked for lentils, they said, 'Do you want wheat now?' Therefore, it is said, 'In vain do they talk to one another.'"In addition, the Talmud teaches that there are those who speak with their lips but their hearts do not agree. They speak one thing but think another. Therefore, it is important to speak truthfully and with honesty, both in word and deed. [References:Babylonian Talmud, Bava Metzia 58b, Jeremiah 9:7 (Tanakh)

Beloved are Israel, whom the Holy One Blessed be He surrounded with (seven) mitzvoth: Tefillin on the head and tefillin on the arm, mezzuzah on their doors, and tzitzith on the four corners of their garments. About them David said (Psalms 119:114) "(For these) seven in the day have I praised you." He entered the bathhouse and saw himself naked — whereupon he said: "Woe unto me that I am 'naked' of mitzvoth," but looking upon his circumcision, he uttered praise, viz. (Ibid. 12:1) "For the chief musician on the eighth, (circumcision, the eighth mitzvah, on the eighth day), a psalm of David."

"Raise a song and strike the tambourine." Rabbi Hiyya bar Abba said, "The nevel (harp) is like a corpse (naveil)." Rabbi Shimon said, "The nevel is for itself, and the kinor (lyre) is for itself, and there are pegs and nails between them." Rav Huna said in the name of Rabbi Assi, "Through the leather that is not worked and through the pegs and nails." And why is it called nevel? Because it makes all kinds of music decay. Rabbi Yehuda bar Rabbi Elai said, "In this world, it is through the pegs and nails (and how many pegs are there between them) that there are seven pegs in the kinor, as it says, 'Seven times a day I praise You' (Psalms 119:164). In the days of the Messiah, there will be eight, as it says, 'For the conductor, on the eighth' (Psalms 12:1). And in the future to come, there will be ten, as it says, 'On me is a decade and a nevel (harp)' (Psalms 92:4)."
