אבות א, יג - ניצול הכתר

(13) He [also] used to say: one who makes his name great causes his name to be destroyed; one who does not add [to his knowledge] causes [it] to cease; one who does not study [the Torah] deserves death; one who makes [unworthy] use of the crown [of learning] shall pass away.

And Rav Yehuda said: Three things curtail a person’s days and years: One who is invited and given the Torah scroll to read and he does not read, one who is given a cup of blessing over which to recite a blessing and he does not recite a blessing, and one who conducts himself with an air of superiority. The Gemara details the biblical sources for these cases: One who is given the Torah scroll to read and he does not read, as it is written of the Torah: “It is your life and the length of your days” (Deuteronomy 30:20). A cup of blessing over which to recite a blessing and he does not recite a blessing, as it is written: “I will bless them that bless you” (Genesis 12:3); one who blesses is blessed and one who does not bless does not merit a blessing. And with regard to one who conducts himself with an air of superiority, as Rabbi Ḥama, son of Rabbi Ḥanina, said: Why did Joseph die before his brothers, as evidenced by the order in the verse: “And Joseph died, and all his brethren, and all that generation” (Exodus 1:6)? Because he conducted himself with an air of superiority, and those who did not serve in a leadership role lived on after he died.

Bar Kapparah opened [his discourse]: "It is You who light my lamp" (Psalms 18:29) - the Holy One, blessed be He, said to Adam, "Your light is in My hands and My light is in your hands." Your light is in My hands, as it is stated (Proverbs 20:27), "The lamp of the Lord is the soul of man"; and My light is in your hands, as it is stated (Leviticus 24:2), "to light a continual lamp." Rather, the Holy One, blessed be He, said, "If you light My lamp, I will certainly light your lamp."
