(לא) וַיַּ֤רְא אֱלֹהִים֙ אֶת־כָּל־אֲשֶׁ֣ר עָשָׂ֔ה וְהִנֵּה־ט֖וֹב מְאֹ֑ד וַֽיְהִי־עֶ֥רֶב וַֽיְהִי־בֹ֖קֶר י֥וֹם הַשִּׁשִּֽׁי׃ (פ)

Genesis 1:31

(31) And God saw all that He had made, and found it very good. And there was evening and there was morning, the sixth day.

ברכות נ״ד א:ו׳

חַיָּיב אָדָם לְבָרֵךְ עַל הָרָעָה כְּשֵׁם שֶׁמְּבָרֵךְ עַל הַטּוֹבָה, שֶׁנֶּאֱמַר: ״וְאָהַבְתָּ אֵת ה׳ אֱלֹהֶיךָ בְּכׇל לְבָבְךָ וְגוֹ׳״. ״בְּכָל לְבָבְךָ״ — בִּשְׁנֵי יְצָרֶיךָ, בְּיֵצֶר טוֹב וּבְיֵצֶר הָרָע. ״וּבְכׇל נַפְשְׁךָ״ — אֲפִילּוּ הוּא נוֹטֵל אֶת נַפְשְׁךָ. ״וּבְכׇל מְאֹדֶךָ״ — בְּכָל מָמוֹנְךָ. דָּבָר אַחֵר: ״בְּכָל מְאֹדֶךָ״ — בְּכָל מִדָּה וּמִדָּה שֶׁהוּא מוֹדֵד לְךָ הֱוֵי מוֹדֶה לוֹ.

Berakhot 54a:6

The mishna articulates a general principle: One is obligated to recite a blessing for the bad that befalls him just as he recites a blessing for the good that befalls him, as it is stated: “And you shall love the Lord your God with all your heart, with all your soul, and with all your might” (Deuteronomy 6:5). The mishna explains this verse as follows: “With all your heart” means with your two inclinations, with your good inclination and your evil inclination, both of which must be subjugated to the love of God. “With all your soul” means even if God takes your soul. “And with all your might” means with all your money, as money is referred to in the Bible as might. Alternatively, it may be explained that “with all your might” means with every measure that He metes out to you; whether it is good or troublesome, thank Him.

עירובין כ״א ב:ג׳

דָּרֵשׁ רָבָא, מַאי דִּכְתִיב: ״הַדּוּדָאִים נָתְנוּ רֵיחַ״ — אֵלּוּ בַּחוּרֵי יִשְׂרָאֵל שֶׁלֹּא טָעֲמוּ טַעַם חֵטְא.

Eruvin 21b:3

Rava interpreted the verse cited above homiletically as follows: What is the meaning of that which is written: “The mandrakes [duda’im] yield a fragrance, and at our doors are all manner of choice fruits, new and old, which I have laid up for you, O my beloved” (Song of Songs 7:14)? “The mandrakes [duda’im] yield a fragrance,” these are the young men of Israel who have never tasted the taste of sin.

ספורנו על בראשית ב׳:כ״ה

(א) ערומים ולא יתבוששו כי אז היו כל פעולותיהם וכל איבריהם לעשות רצון קונם בלבד לא להשיג תענוגות נפסדות כלל באופן שהית' פעולת הזיווג אצלם כפעולת האכילה והשתיה המספקת ובכן היה ענין איברים ההם אצלם כמו ענין הפה והפנים והידים אצלנו:

Sforno on Genesis 2:25

(1) And they were not ashamed. They used their limbs solely for the service of their Maker, not the pursuit of base pleasures. Therefore they considered marital relations no different than eating and drinking and their reproductive organs no different than their mouth or hands.

קידושין ל׳ ב:ז׳

ואמר ר"ש בן לוי יצרו של אדם מתגבר עליו בכל יום ומבקש המיתו שנאמר (תהלים לז, לב) צופה רשע לצדיק ומבקש להמיתו ואלמלא הקב"ה עוזרו אין יכול לו שנאמר אלהים לא יעזבנו בידו

Kiddushin 30b:7

And Rabbi Shimon ben Levi says: A person’s inclination overpowers him every day, and seeks to kill him, as it is stated: “The wicked watches the righteous and seeks to slay him” (Psalms 37:32). And if not for the fact that the Holy One, Blessed be He, assists each person in battling his evil inclination, he could not overcome it, as it is stated: “The Lord will not leave him in his hand” (Psalms 37:33).

סנהדרין ק״ז א:ד׳

אמר רב יהודה שהפך משכבו של לילה למשכבו של יום ונתעלמה ממנו הלכה אבר קטן יש באדם משביעו רעב ומרעיבו שבע

Sanhedrin 107a:4

Rav Yehuda says: Once David heard the nature of his ordeal, he sought to prevent himself from experiencing lust. He transformed his nighttime bed into his daytime bed, i.e., he engaged in intercourse with his wives during the day, in an attempt to quell his lust. But a halakha, i.e., a Torah statement, escaped him: There is a small limb in man that he employs in sexual intercourse. If he starves the limb, and does not overindulge, it is satiated; but if he satiates the limb and overindulges in sexual intercourse, it is starving, and desires more. Therefore, his plan had the opposite effect.

Mishneh Torah, Human Dispositions 3:1

(1) Peradventure man will say: Seeing that envy, desire and vainglory and like tendencies are evil tendencies and remove man from life, I will separate myself from them exceedingly and reach their remotest extreme. Until he will eat no meat, drink no wine, marry no woman, dwell in no comfortable quarters, dress in no proper clothes but in a sack and coarse wool, and the like, as for instance the idolatrous priests do. Even such is an evil way, and it is forbidden to follow it. He who follows this way is called a sinner, for it is said of a Nazarite: "And make an atonement for him, because he hath sinned against the soul" (Num. 6.11), whereupon the sages said: "If the Nazarite, who did not separate himself from aught but wine must have atonement, he who deprives himself from each and every thing how manifold must his atonement be" (Baba Kama. 91b)!¹See Ta’anit, 11a. G. Therefore did the sages command, saying: A man shall not deprive himself of ought save the things which the Torah itself deprived him of; nor shall he bind himself by vows and oaths to abstain from things which are permitted. They have even said: "Is it not enough for thee what the Torah has forbidden, that thou doest forbid thyself even other things" (Yeru. Nedarim. 7.37)? And in this rule are included such who are continuously fasting, for they are not in the good way, and the sages prohibited one from punishing himself with fast days. Concerning such and like matters Solomon admonished saying: "Be not righteous overmuch; neither show thyself wise; why wouldst thou destroy thyself" (Ecc. 7.16).

Ecclesiastes 3:11

(11) He brings everything to pass precisely at its time; He also puts eternity in their mind, but without man ever guessing, from first to last, all the things that God brings to pass.
