Tossefta sur La Genèse 3:14

וַיֹּאמֶר֩ יְהֹוָ֨ה אֱלֹהִ֥ים ׀ אֶֽל־הַנָּחָשׁ֮ כִּ֣י עָשִׂ֣יתָ זֹּאת֒ אָר֤וּר אַתָּה֙ מִכָּל־הַבְּהֵמָ֔ה וּמִכֹּ֖ל חַיַּ֣ת הַשָּׂדֶ֑ה עַל־גְּחֹנְךָ֣ תֵלֵ֔ךְ וְעָפָ֥ר תֹּאכַ֖ל כָּל־יְמֵ֥י חַיֶּֽיךָ׃

L’Éternel-Dieu dit au serpent "Parce que tu as fait cela, tu es maudit entre tous les animaux et entre toutes les créatures terrestres: tu te traîneras sur le ventre, et tu te nourriras de poussière tous les jours de ta vie.

Tosefta Sotah

Just as she is forbidden to her husband, so too is she forbidden to her paramour (Sot. 5:1). Therefore, it is said regarding a suspected adulteress, that she cast her eyes on what was not fit for her, [and as a result] that which she sought was not given to her, and that which was in her hands was taken from her. And so too you find with the primeval snake, that it was craftier than all the animals and all the beasts of the field, as it is said (Gen. 3:1), "And the snake was craftier than all [the beasts], etc." It sought to kill Adam and marry Eve. The Place said to it, I said, you will be the king of all the animals and beasts, and now, since you did not desire that, you will be more accursed than all the animals and all the beasts of the field. I said, you will walk tall and upright, like a man. Now, since you did not desire that, "on your belly you will crawl" (Gen. 3:14). I said, you will eat from the food of man, and drink from the drink of man. Now, since you did not desire that, "and dust you shall eat all the days of your life" (ibid.). You sought to kill Adam and marry Eve. Now, "and enmity I will place between you and the woman" (Gen. 3:15). Thus, that which it sought was not given to it, and that which was in its hand was taken from it, and so too you find with Cain, Korach, and Bilaam, and Doeg, and Ahitophel, and Gahazi, and Absalom, and Adonijah, and Haman, that they cast their eyes on what was not fit for them. That which they sought was not given to them, and that which was in their hands was taken from them.
