וּמוֹרַאֲכֶ֤ם וְחִתְּכֶם֙ יִֽהְיֶ֔ה עַ֚ל כָּל־חַיַּ֣ת הָאָ֔רֶץ וְעַ֖ל כָּל־ע֣וֹף הַשָּׁמָ֑יִם בְּכֹל֩ אֲשֶׁ֨ר תִּרְמֹ֧שׂ הָֽאֲדָמָ֛ה וּֽבְכָל־דְּגֵ֥י הַיָּ֖ם בְּיֶדְכֶ֥ם נִתָּֽנוּ׃
E o temor e o pavor de vós estará sobre toda a criatura da terra, e sobre todas as aves dos céus, em tudo o que se move sobre o solo e em todos os peixes do mar; eles foram entregues nas vossas mãos.
Rabbeinu Bahya
ויחל העם, “the people profaned themselves.” The word ויחל means to profane something which previously was sacred, holy. We encounter the same word in connection with Noach (Genesis 9,2), when Noach planted a vineyard and became drunk. Judaism describes people who are meticulous in their sexual mores as ”holy,” whereas those that are not are considered as “profane.” Whenever the Torah refers to the Israelites simply as העם, this term implies a criticism of their spiritual level (at that time). The Following are some examples of the Torah using this terminology: Numbers 11,1: “the people were looking for something to complain about.” Numbers 20,3: “the people quarrelled.” Numbers 21,5: “the people spoke out against G’d.” On the other hand, whenever the people of Israel are referred to as עמי, this is to be taken as a complimentary term; examples are: Psalms 81,14: “if only My people would listen to Me.” Exodus 7,4: “I will take out the hosts of My people.” Isaiah 40,1: “comfort, comfort My people.”
Radak
Thou hast put all things under his feet: – The lower (beings) are all under him, as it says (Gen. 9:2): “And the fear of you and the dread of you shall be upon every beast of the earth and upon every fowl of the air.'”
Rashi
וישם ה' לקין אות AND THE LORD SET A SIGN FOR CAIN — He inscribed on his forehead a letter of His Divine Name (Pirkei DeRabbi Eliezer 21). Other editions of Rashi add the following: another interpretation of “Whoever will find me will slay me”: this refers to cattle and beasts, since there were then no human beings in the world of whom he might be afraid except his father and mother, and, of course, he did not fear that they would slay him. He, therefore, said, “Until now the fear of me was upon all animals — as it is written”, (Genesis 9:2) “And the fear of you shall be upon all beasts of the field” etc. — now, however, because of my sin the animals will no longer fear me and will kill me. God immediately set a sign for Cain, viz., he again made the animals be in fear of him.
