וְשָׁמַעְתָּ֤ יִשְׂרָאֵל֙ וְשָׁמַרְתָּ֣ לַעֲשׂ֔וֹת אֲשֶׁר֙ יִיטַ֣ב לְךָ֔ וַאֲשֶׁ֥ר תִּרְבּ֖וּן מְאֹ֑ד כַּאֲשֶׁר֩ דִּבֶּ֨ר יְהוָ֜ה אֱלֹהֵ֤י אֲבֹתֶ֙יךָ֙ לָ֔ךְ אֶ֛רֶץ זָבַ֥ת חָלָ֖ב וּדְבָֽשׁ׃ (פ)
Послушай, Израиль, и соблюдай; чтобы тебе было хорошо, и чтобы ты могильно умножился, как обещал тебе Господь, Бог отцов твоих—земля течет с молоком и медом.
Mekhilta DeRabbi Yishmael
The sea has no heart, and He gave it a heart. A terebinth has no heart, and He gave it a heart, viz. (II Samuel 18:4) "He (Avshalom) was yet alive in the heart of the terebinth." The heavens have no heart, and He gave them a heart, viz. (Devarim 4:11) "And the mountain (Sinai) burned with fire until the heart of heaven." Let the sea come, which had no heart and was given a heart, and exact payment of the Egyptians, who had a heart and subjugated Israel with all kinds of ("heartless") torments, viz. (Exodus 1:13) "And Egypt subjected the children of Israel to grueling toil." Let the terebinth come, which had no heart and was given a heart and exact punishment of Avshalom, who had a heart and "stole" three hearts — the heart of his father, the heart of beth-din, and the heart of Israel, viz. (II Samuel 15:6) ("And Avshalom did this) … and Avshalom stole the heart of the men of Israel." Let the heavens come, which have no heart and were given a heart, and drop manna like dew upon Israel, who had a heart and accepted the Torah and served the L–rd with all their hearts and all their souls, viz. (Devarim 6:3) "And you shall love the L–rd your G–d with all of your heart and all of your soul, etc."
Midrash Tehillim
You commanded your commandments to be kept diligently. Everywhere that God commanded about the Torah, He commanded them about the Torah. He commanded them in the prophets. He commanded them in the writings. And God said, "Have I not written for you thirty sayings of counsel and knowledge?" (Proverbs 22:20). And He also said, "Hear, O Israel, and be careful to do them" (Deuteronomy 6:3). And He said, "Only take care, and keep your soul diligently" (Deuteronomy 4:9). What is "take care"? God said, "If you keep the Torah, I will keep your soul" (Talmud, Shabbat 127a). Therefore it is said, "Take care and keep your soul diligently all the days of your life" (Deuteronomy 4:9). What are "all the days of your life"? If you do the Torah all the days of your life, you will merit to see children and grandchildren. Therefore it is said, "And you shall teach them to your children and your grandchildren" (Deuteronomy 4:9). And if you see children and grandchildren, then there will be peace, as it is said, "May you see your children's children! Peace be upon Israel!" (Psalms 128:6).
