7. There are seven things that characterize a boor, and seven that characterize a wise man. A wise man does not speak before one who is greater than him in wisdom or age. He does not interrupt his fellow's words. He does not hasten to answer. His questions are on the subject and his answers to the point. He responds to first things first and to latter things later. Concerning what he did not hear, he says "I did not hear." He concedes to the truth. With the boor, the reverse of all these is the case. 9. Carnage by wild beasts comes to the world for false oaths and the desecration of G‑d's name. Exile comes to the world for idol-worship, sexual promiscuity, murder and the failure to leave the land fallow on the sabbatical year. 10. There are four types of people: One who says, "What is mine is yours, and what is yours is mine" is a boor. One who says "What is mine is mine, and what is yours is yours" — this is a median characteristic; others say that this is the character of a Sodomite. One who says, "What is mine is yours, and what is yours is yours" is a chassid (pious person). And one who says "What is mine is mine, and what is yours is mine" is wicked. 11. There are four types of temperaments. One who is easily angered and easily appeased—his virtue cancels his flaw. One whom it is difficult to anger and difficult to appease—his flaw cancels his virtue. One whom it is difficult to anger and is easily appeased, is a chassid. One who is easily angered and is difficult to appease, is wicked. 12. There are four types of student. One who is quick to understand and quick to forget—his flaw cancels his virtue. One who is slow to understand and slow to forget—his virtue cancels his flaw. One who is quick to understand and slow to forget—his is a good portion. One who is slow to understand and quick to forget—his is a bad portion. 13. There are four types of contributors to charity. One who wants to give but does not want others to give—is begrudging of others. One who wants that others should give but does not want to give—begrudges himself. One who wants that he as well as others should give, is a chassid. One who want neither himself nor others to give, is wicked. 14. There are four types among those who attend the study hall. One who goes but does nothing—has gained the rewards of going. One who does [study] but does not go to the study hall—has gained the rewards of doing. One who goes and does, is a chassid. One who neither goes nor does, is wicked. 15. There are four types among those who sit before the sages: the sponge, the funnel, the strainer and the sieve. The sponge absorbs all. The funnel takes in at one end and lets it out the other. The strainer rejects the wine and retains the sediment. The sieve rejects the coarse flour and retains the fine flour. 16. Any love that is dependent on something—when the thing ceases, the love also ceases. But a love that is not dependent on anything never ceases. What is [an example of] a love that is dependent on something? The love of Amnon for Tamar. And one that is not dependent on anything? The love of David and Jonathan. 17. Any dispute that is for the sake of Heaven is destined to endure; one that is not for the sake of Heaven is not destined to endure. Which is a dispute that is for the sake of Heaven? The dispute(s) between Hillel and Shamai. Which is a dispute that is not for the sake of Heaven? The dispute of Korach and all his company. 18. One who causes the community to be meritorious, no sin will come by his hand. One who causes the community to sin, is not given the opportunity to repent. Moses was meritorious and caused the community to be meritorious, so the community's merit is attributed to him; as is stated, "He did G‑d's righteousness, and His laws with Israel" (Deuteronomy 33:21). Jeroboam the son of Nebat sinned and caused the community to sin, so the community's sin is attributed to him; as is stated, "For the sins of Jeroboam, which he sinned and caused Israel to sin" (I Kings 15:30). 20. Judah the son of Teima would say: Be bold as a leopard, light as an eagle, fleeting as a deer and mighty as a lion to do the will of your Father in Heaven. He would also say: The brazen—to purgatory; the bashful—to paradise. May it be Your will, L-rd our G‑d and G‑d of our fathers, that the Holy Temple be rebuilt speedily in our days; and grant us our portion in Your Torah. 21. Ben Bag Bag would say: Delve and delve into it, for all is in it; see with it; grow old and worn in it; do not budge from it, for there is nothing better. Ben Hei Hei would say: According to the pain is the gain. ... https://www.youtube.com/watch?v=pQO2-bcPyN4
