Midras Habakuk 3:14: Mekhilta DeRabbi Yishmael, Midrash Tanchuma & Midrash Tehillim

R. Eliezer b. Yehudah of Bortutha says: In the merit of the tribes I will split the sea for them, viz. (Habakkuk 3:14) "You have split (the sea) for his tribes, the heads of his scattered ones, etc." And it is written (Psalms 136:13) "who split the sea into sections."

"And you, raise your staff": Ten miracles were performed for Israel at the sea: The waters were split and became like a dome, viz. (Habakkuk 3:14) "You split (the sea) for his tribes; the summit of its scattering raged to scatter me"; the sea became dry land, viz. (Exodus 14:29) "and the children of Israel walked on the dry land"; it became like tar (where the Egyptians trod), viz. (Habakkuk, Ibid. 15) "You led your horses in the sea, in the mire of many waters"; it (the water) became like crumbs, viz. (Psalms 74:13) "You 'crumbed' the sea with Your might"; it became like rocks, viz. (Ibid.) "You broke the heads of serpents (the Egyptians) on the waters"; the sea split into sections, viz. (Ibid. 136:13) "You split the Red Sea into sections," viz. (Ibid. 15:8) "and with the breath of Your nostrils the waters piled up"; they became like a wall, viz. (Ibid.) "the waves stood up as a wall"; He extracted for them sweets from salts, viz. (Psalms 78:16) "and He brought forth streams from a rock and brought down waters as rivers"; He froze the sea for them and it became like vessels of glass, viz. (Exodus 15:8) "The depths froze in the midst of the sea."

And lift thou up thy rod (Exod. 14:16). Ten miracles were performed in their behalf at the sea. The sea was split asunder for them, and became a kind of vault, as it is said: Thou hast struck through with his own rods the heads, etc. (Hab. 3:14). It was divided into twelve paths, as it is said: And stretch out thy hand over the sea and divide it (Exod. 14:16). It was turned into dry land, as it is said: And the children of Israel walked upon dry land the midst of the sea (ibid., v. 29). It was converted into a kind of clay, as is said: Thou hast trodden the sea with thy horses, the mud of mighty waters (Hab. 3:15). The water was made into pieces, as it is said: Thou didst break the sea into pieces by Thy strength (Ps. 74:13). It was changed into rocks, as is said: Thou didst shatter the heads of the sea monsters in the waters (ibid.). It was torn asunder, as it is said: To him who divided the Red Sea asunder (ibid. 136:13). It was piled up into stacks, as it is said: And with the blast of Thy nostrils, the waters were piled up (Exod. 15:8). It was made into a heap, as is said: Stood upright like a heap (ibid.). Barrels of sweet water flowed out of the salt water for them, and the sea congealed and became like a glass vessel, as it is said: The deeps were congealed (ibid.).
