Sirach 21:22
Ben Sira, Ecclesiasticus19 To a senseless person education is fetters on his feet, and like manacles on his right hand. 20 A fool raises his voice when he laughs, but the wise smile quietly. 21 To the sensible person education is like a golden ornament, and like a bracelet on the right arm. 22 The foot of a fool rushes into a house, but an experienced person waits respectfully outside. 23 A boor peers into the house from the door, but a cultivated person remains outside. 24 It is ill-mannered for a person to listen at a door; the discreet would be grieved by the disgrace.
Niddah 16b
Babylonian TalmudThe Gemara asks: And Rabbi Yoḥanan, how does he interpret that verse cited by Reish Lakish? The Gemara answers that Rabbi Yoḥanan requires that verse: “But he who despises his ways shall die,” to teach that which is written in the book of ben Sira: Three people I have hated, and a fourth I have not loved: A minister who frequents [hanirgal] drinking houses, as he disgraces himself and leads himself to ruin and death; and some say a different version of the text: A minister who chats [hanirgan] in drinking houses; and some say a third version: A minister who is short-tempered [hanirgaz] when in drinking houses. That is the first that he hated. And the others are one who dwells at the highest point of the city, where everyone sees him; and one who holds his penis and urinates. And the fourth, whom he has not loved, is one who enters the house of another suddenly, without warning. Rabbi Yoḥanan says: And this includes even one who comes into his own house without prior warning, as the members of his household might be engaged in private activities.
