Midrash su Geremia 18:17

..."And the waters were a wall for them" Made them as a type of wall. "On their right and on their left" On their right due to the merit of the Torah that they would in the future receive through the right, as it is said "From His right, a fiery law to them" (Deut. 33:2). And on their left: this is prayer.

(Exodus 14:21) "And the L rd drove the sea with a strong east wind all the night": the strongest of the winds, the east wind. And thus you find that the L rd exacted punishment of the men of the generation of the flood and of the men of Sodom with a strong east wind, viz. (Iyyov 4:9) "By the breath of G d they go lost, and by the wind of His wrath they perish": "By the breath of G d they go lost" — the generation of the flood; "and by the wind of His wrath they perish" — the generation of Sodom. And thus do you find with the generation of the tower of Bavel, that the L rd exacted punishment of them with a strong east wind, viz. (Genesis 11:8) "And from there the L rd scattered them on the face of all the earth," "scattering" connoting an east wind, viz. (Jeremiah 18:17) "With an east wind I will scatter them." And thus with Egypt, viz. (Exodus 10:15) "And the L rd swept an east wind over the land." And thus do you find with the ten tribes, that the L rd exacted punishment of them with an east wind, viz. (Hoshea 13:15) "For he (Ephraim) flourished among the reeds. (But now) an east wind will come, a wind from the L rd, rising from the desert, and it will dry up his source and parch his spring. It will despoil the source of all his precious vessels." And thus do you find with the tribes of Judah and Benjamin, that the L rd exacted punishment of them with an east wind, viz. (Jeremiah 18:17) "With an east wind I will scatter them." And thus do you find with Tyre, that He exacted punishment of them with an east wind, viz. (Ezekiel 27:26) "and the east wind has broken you in the heart of the seas." And thus you find that the Holy One Blessed be He is destined to exact punishment of "the merry kingdom" (Tarshish), viz. (Psalms 48:8) "With an east wind You will smash the ships of Tarshish." And thus do you find that the Holy One Blessed be He is destined to exact punishment of the wicked in Gehinnom with the east wind, viz. (Isaiah 30:33) "For Tafteh (Gehinnom) is ready from yesterday. It is readied for the king (Sancheriv). He has deepened and widened it. Its pyre has much fire and wood. The breath of the L rd, as a stream of sulfur, burns in it." And it is written (Ibid. 27:8) "He spoke His stern words on the day of the east wind." Here, too, "And the L rd drove the sea with a strong east wind": the strongest of the winds, the east wind.
