"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."
