התבגרות ונעורים - "יצר לב האדם רע מנעוריו"

And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt-offerings on the altar. And the LORD smelled the sweet savour; and the LORD said in His heart: ‘I will not again curse the ground any more for man’s sake; for the imagination of man’s heart is evil from his youth; neither will I again smite any more every thing living, as I have done.

Rabbi Yehoshua would say: The Evil Eye, the Evil Urge, and the hatred of others take a person out of the world. The Evil Eye. How so? This teaches that a person should regard his friend’s household just as he regards his own household. And just as a person does not want people to say disparaging things about his wife and children, so he should not want people to say disparaging things about his friend’s wife and children. Another interpretation: The Evil Eye. How so? A person should not look askance at his friend’s learning. There is a story of someone who looked askance at his friend’s learning, and his life was cut short, and he reached his end prematurely and passed on from the world. The Evil Urge. How so? They say that for the first thirteen years [of a person’s life] the Evil Urge is greater than the Good Urge. There in his mother’s womb, a person’s Evil Urge grows with him. [After he emerges into the world,] he starts breaking the Sabbath, and nothing is there to stop him; [killing people, and nothing is there to stop him; going out to sin, and nothing is there to stop him.]
After thirteen years, the Good Urge is born. Then when he breaks the Sabbath, it says to him: Empty one! Isn’t it written (Exodus 31:14), “One who breaks it will surely die”? When he kills, it says to him: Empty one! Isn’t it written (Genesis 9:6), “One who spills the blood of a person, his own blood will be spilled”? When he goes out to sin, it says to him: Empty one! Isn’t it written (Leviticus 20:16), “Both the adulterer and the adulteress shall be put to death”?
When a person heats himself up, and then goes to commit some act of lewdness, all of his limbs will obey him, because the Evil Urge rules over all 248 limbs. When he goes to perform a mitzvah, his limbs begin to grow lazy, because the Evil Urge in his stomach rules over all 248 of a person’s limbs. The Good Urge, meanwhile, is like someone trapped in a prison, as it says (Ecclesiastes 4:14), “From the prison, he comes forth to rule” – that is the Good Urge.
Some say, that verse refers to Joseph the Righteous, when that wicked woman came and tortured him with words. She said to him: I will lock you up in prison! He said to her: But God releases the bound. She said to him: I will poke out your eyes! He said: God gives sight to the blind. She said to him: I will bend you down! He said to her: God straightens the bent. (She said to him: I will make you into a wicked man! He said to her: God loves the righteous. She said to him: I will make you an Aramean! He said to her: God protects the strangers. Until finally he said [Genesis 39:9], “How can I do this evil thing?”)
And do not be surprised at Joseph the Righteous. For behold, Rabbi Tzadok was the greatest of his generation when he was captured. And a matron took him and presented before him a beautiful maidservant. When he saw her, he turned his eyes to the wall so he would not see her. And he sat and recited his learning the whole night. In the morning, the maidservant left and complained to her mistress: I would rather die than be given to that man! The matron sent for him and said to him: Why didn’t you do with this woman as all people do? He said to her: What can I do? I come from the lineage of the high priest, from a great family! I said to myself, Perhaps I will sleep with her and increase mamzerim in Israel! When she heard this, she commanded he be released with great honor. (And they say:) Do not be surprised at Rabbi Tzadok. For behold, Rabbi Akiva was greater than him! When he went to Rome, informers slandered him to a local prefect, who then presented before him two beautiful women. [The prefect] bathed and anointed them dressed them up like brides, and they fell upon [Rabbi Akiva] the whole night. This one said: Come to me! And that one said: Come to me! But he sat between them and spat, and would not turn to them. They went before the prefect and said to him: We would rather die than be given to that man! He sent for [Rabbi Akiva] and said to him: Why didn’t you do with those women as all people do with women? Weren’t they beautiful? And weren’t they human beings just like you? Didn’t the One who created you create them as well? [Rabbi Akiva] said: What could I do? Their scent was worse to me than carcasses and vermin! And do not be surprised at Rabbi Akiva. For behold, Rabbi Eliezer the Great was greater than him. For he raised his sister’s daughter until she was thirteen, and she slept in bed with him until she began puberty. Then he said to her: Go, and marry a man. She said to him: Am I not your woman? Should I be given as a maidservant to wash the legs of your students? He said to her: My daughter, I am already an old man. Go and marry a young man like yourself. She said to him: Didn’t I already say to you, Am I not your woman? Should I be given as a maidservant to wash the legs of your students? When he heard her words, he got permission from her to marry her, and then had sexual relations with her.

And it came to pass in those days, when Moses was grown up, that he went out unto his brethren, and looked on their burdens; and he saw an Egyptian smiting a Hebrew, one of his brethren. And he looked this way and that way, and when he saw that there was no man, he smote the Egyptian, and hid him in the sand. And he went out the second day, and, behold, two men of the Hebrews were striving together; and he said to him that did the wrong: ‘Wherefore smitest thou thy fellow?’ And he said: ‘Who made thee a ruler and a judge over us? thinkest thou to kill me, as thou didst kill the Egyptian?’ And Moses feared, and said: ‘Surely the thing is known.’ Now when Pharaoh heard this thing, he sought to slay Moses. But Moses fled from the face of Pharaoh, and dwelt in the land of Midian; and he sat down by a well. Now the priest of Midian had seven daughters; and they came and drew water, and filled the troughs to water their father’s flock. And the shepherds came and drove them away; but Moses stood up and helped them, and watered their flock. And when they came to Reuel their father, he said: ‘How is it that ye are come so soon to-day?’ And they said: ‘An Egyptian delivered us out of the hand of the shepherds, and moreover he drew water for us, and watered the flock.’
