Midrasz do Rodzaju 1:10

2) "All that have fins and scales in the waters, in the seas, and in the rivers — those may you eat': "in the seas (yamim)": This is the Great Sea (the Mediterranean), as it is written (Bereshith 1:10): "And the (great) ingathering of the waters, He called yamim." "and in the nechalim": These are the rivers, as it is written (Bereshith 2:10): "And a river went out of Eden to water the garden." This tells me only of oceans and rivers, that flow (both) in the dry season and in the rainy season. Whence do I derive for inclusion other waters, and other rivers, that flow in the rainy season but not in the dry season, until you include water in holes? From (the repetition of) "in the waters" (Bereshith 11:8, Bereshith 11:9).

THE GATHERING OF THE WATERS
ON the third day all the earth was flat like a plain and the waters covered the surface of all the earth. When the word of the Almighty was uttered, "Let the waters be gathered together" (Gen. 1:9), the mountains and hills arose from the ends of the earth and they were scattered over the surface of all the earth, and valleys were formed over the inner parts of the earth; and the waters were rolled together and gathered into the valleys, as it is said, "And the gathering together of the waters he called seas" (Gen. 1:10). Forthwith the waters became proud and they arose to cover the earth as at first, when the Holy One, blessed be He, rebuked them || and subdued them, and placed them beneath the soles of His feet, and measured them with the hollow of His hand that they should neither decrease nor increase. He made the sand as the boundary of the sea, just like a man who makes a fence for his vineyard. When they rise and see the sand before them they return to their former place, as it is said, "Fear ye not me? saith the Lord: will ye not tremble at my presence, which have placed the sand for the bound of the sea?" (Jer. 5:22).

(Exod. 37:1:) THEN BEZALEL MADE THE ARK. This text is related (to Ps. 119:130): THE OPENING OF YOUR WORDS ENLIGHTEN; IT GIVES UNDERSTANDING TO THE SIMPLE. R. Simeon [ben Jehozadak] asked R. Samuel bar {Nehemiah} [Nahman]: < Since > you are a master of Haggadah, tell me: How did the Holy One create the world?²⁸Tanh., Exod. 10:6; Gen. R. 3:4; Exod. R. 50:1; Lev. R. 31:7; M. Pss. 104:4. He said to him: When the Holy One wanted to create the world, he wrapped himself in light and created his world, as stated (in Ps. 104:2): WHO PUTS ON LIGHT LIKE A GARMENT.²⁹See above, Tanh. (Buber), Gen. 1:10. After that (in the same vs.): WHO SPREADS OUT THE HEAVENS LIKE A SHEET. Therefore (in Ps. 119:130): THE OPENING OF YOUR WORDS ENLIGHTEN…. R. Judah said: To what is the matter comparable? To a king {who had} [who wanted to build himself] a palace,³⁰Lat.: palatium; Gk.: palation. but that place was {one of} darkness.³¹Cf. Gen. R.3:1. What did he do? He lit the lamps, and afterwards he built a palace. So when the Holy One built the world, it was all darkness. What did he do? He wrapped himself in light and created it. Ergo (in Exod. 119:130): THE OPENING (PTH) OF YOUR WORDS ENLIGHTEN…. From the Holy One the righteous have learned that they should begin <any task> in light. When the Holy One said to him (i.e., to Moses in Exod. 25:8): AND LET THEM MAKE ME A SANCTUARY, Moses told Bezalel to make a Tabernacle. With what did he first begin (PTH)? The work on the Ark. (Exod. 37:1:) THEN BEZALEL MADE THE ARK.

R. Yossi Hameshulam says: Whence is it derived that just as it (Eretz Yisrael) imparts flavors to the land, so it imparts flavors to the sea (i.e., the Mediterranean)? From (Bereshith 11:10) "and the gathering of the waters He called "'seas.'" Now the sea is one, viz. (Ibid. 9) "Let the waters under the heavens be gathered into one place." How, then, is "and the gathering of the waters He called 'seas'" to be understood? (It is to be understood as meaning) that the flavor of a fish brought up from Acco is not like that of one brought up from Tzor, and that the flavor of a fish brought up from Tzor is not like that of one brought up from Spain.
