מַה־לְּךָ֣ הַ֭יָּם כִּ֣י תָנ֑וּס הַ֝יַּרְדֵּ֗ן תִּסֹּ֥ב לְאָחֽוֹר׃
바다야 네가 도망함은 어찜이며 요단아 네가 물러감은 어찜인고
Zohar
It was taught, Rabbi Yitzḥak says: When the Holy One Blessed is He was revealed on Mount Sinai, the mountain quaked. When Sinai quaked, all the other mountains of the world quaked. They were going up and down until the hand of the Holy One Blessed is He pressed on them, and they stayed still. Then a voice went forth and proclaimed (Tehillim 114:5-6) "What alarmed you, O sea, that you fled, Jordan, that you ran backward, mountains, that you skipped like rams, etc".
