From the sources
וְהַנָּחָשׁ֙ הָיָ֣ה עָר֔וּם מִכֹּל֙ חַיַּ֣ת הַשָּׂדֶ֔ה אֲשֶׁ֥ר עָשָׂ֖ה יְהוָ֣ה אֱלֹהִ֑ים וַיֹּ֙אמֶר֙ אֶל־הָ֣אִשָּׁ֔ה אַ֚ף כִּֽי־אָמַ֣ר אֱלֹהִ֔ים לֹ֣א תֹֽאכְל֔וּ מִכֹּ֖ל עֵ֥ץ הַגָּֽן׃
Now the serpent was the shrewdest of all the wild beasts that the LORD God had made. He said to the woman, “Did God really say: You shall not eat of any tree of the garden?”
וַתֹּ֥אמֶר הָֽאִשָּׁ֖ה אֶל־הַנָּחָ֑שׁ מִפְּרִ֥י עֵֽץ־הַגָּ֖ן נֹאכֵֽל׃
The woman replied to the serpent, “We may eat of the fruit of the other trees of the garden.
וּמִפְּרִ֣י הָעֵץ֮ אֲשֶׁ֣ר בְּתוֹךְ־הַגָּן֒ אָמַ֣ר אֱלֹהִ֗ים לֹ֤א תֹֽאכְלוּ֙ מִמֶּ֔נּוּ וְלֹ֥א תִגְּע֖וּ בּ֑וֹ פֶּן־תְּמֻתֽוּן׃It is only about fruit of the tree in the middle of the garden that God said: ‘You shall not eat of it or touch it, lest you die.’”
וַיֹּ֥אמֶר הַנָּחָ֖שׁ אֶל־הָֽאִשָּׁ֑ה לֹֽא־מ֖וֹת תְּמֻתֽוּן׃
And the serpent said to the woman, “You are not going to die,
כִּ֚י יֹדֵ֣עַ אֱלֹהִ֔ים כִּ֗י בְּיוֹם֙ אֲכָלְכֶ֣ם מִמֶּ֔נּוּ וְנִפְקְח֖וּ עֵֽינֵיכֶ֑ם וִהְיִיתֶם֙ כֵּֽאלֹהִ֔ים יֹדְעֵ֖י ט֥וֹב וָרָֽע׃but God knows that as soon as you eat of it your eyes will be opened and you will be like divine beings who know good and bad.”
וַתֵּ֣רֶא הָֽאִשָּׁ֡ה כִּ֣י טוֹב֩ הָעֵ֨ץ לְמַאֲכָ֜ל וְכִ֧י תַֽאֲוָה־ה֣וּא לָעֵינַ֗יִם וְנֶחְמָ֤ד הָעֵץ֙ לְהַשְׂכִּ֔יל וַתִּקַּ֥ח מִפִּרְי֖וֹ וַתֹּאכַ֑ל וַתִּתֵּ֧ן גַּם־לְאִישָׁ֛הּ עִמָּ֖הּ וַיֹּאכַֽל׃
When the woman saw that the tree was good for eating and a delight to the eyes, and that the tree was desirable as a source of wisdom, she took of its fruit and ate. She also gave some to her husband, and he ate. (Bereishit 3:1-6)
In chapter 3, we learn that the snake enticed Chava to eat from the Eitz HaDaat, the tree of knowledge of good and evil. She in turn gave it to Adam HaRishon, who ate as well.
How to eat it
My kids are always looking for ways to include lollies (candy/sweets) in the parsha food. So this is an easy week for them: Jelly Snakes for dessert, anyone?
