Midrash su Esodo 14:11

"against Suf": We are hereby taught that he rebuked them for what they did at the Red Sea (viz. Shemoth 14:11). R. Yehudah says: They rebelled in the midst of the sea, and they rebelled upon ascending from the sea, turning their backs upon Moses and traveling three journeys, viz. (Psalms 106:7) "And they rebelled at the sea, in the sea of Suf": — "at the Sea," upon ascending from it; — "in the sea," in its very midst. I might think that he rebuked them only at the beginning of a journey. Whence do I derive (that he also did so) between journey and journey? From "between Paran" and "between Tofel." "tofel and lavan (white)": They spoke vain words ("divrei tifluth" [as in "tofel"]) against the manna, saying that it was "white" (i.e. insubstantial), viz. (Bamidbar 21:5) "and our soul loathes this 'light' bread" — whereupon he said to them: "Fools, the very essence of kings is that they are fed only 'light' bread, so they not be seized with diarrhea — but you have grumbled at the good that I have given you, following the precedent of your father (Adam). I told him that I would make a helpmate for him (Bereshith 2:18), and for this good that I granted him he grumbled against Me, (Ibid. 3:12) 'The woman that You gave to me — she gave me from the tree and I ate.'"

(Devarim, Ibid.) "and an abundance of gold" (an allusion to the golden calf): He said to them: This thing outweighs all that you have done. The golden calf weighs upon Me more than all! Rebbi was wont to say: An analogy: One caused his neighbor many troubles. In the end, he added an additional trouble, and the other said: This outweighs everything you have done to me. This weighs upon me more than all! Thus did the Holy One Blessed be He say to Israel: This outweighs everything that you have done! Variantly: "and an abundance of gold": R. Shimon b. Yochai says: An analogy: One received sages and disciples, and all praised him. Then Canaanites came, and he received them! — at which they said: This is the man's nature — to receive all! Thus did Moses say to Israel: (You gave) "an abundance of gold" for the mishkan (the tabernacle) — (You gave) "an abundance of gold" for the golden calf! R. B'na'ah says: Israel served idolatry, for which they are liable to extinction — Let the gold of the mishkan atone for the gold of the calf! R. Yossi berebbi Chanina says: It is written "in the desert, in the plain": This alludes to the ten trials wherewith our fathers tried the Holy One Blessed be He in the desert: two at the (Red) sea, (in the descent [Shemoth 14:11] and in the ascent [Psalms 106:7]), two, with water, (at Marah [Shemoth 15:23] and at Refidim [Shemoth 17]), two with manna, ("Let no man go out of his place" [Shemoth 17:29] and "Let no man leave of it" [Shemoth 16:19]), two with the quail, (the first [16:3] and the second [Bamidbar 11:4]), one with the golden calf (Shemoth 32), and one with the spies (Bamidbar 13). R. Yossi b. Dormaskith said to him: Yehudah berebbi, why do you distort the verses for us (by assigning allegorical interpretations to what are really place names)? I testify by heaven and earth that we have reviewed all of the sources and (we have found that) they are all place names. It is just that they were thus named (as aforementioned) because of an event (that transpired there).
