תּלמוד אויף דברים 33:19

Zevulun complained to the Holy One, blessed be he, saying: Master of the Universe! You gave my brothers fields and vineyards and to me you gave hills and mountains. You gave my brothers lands, and to me You gave lakes and rivers. [God] replied: They will all require you for the hilazon, as it says, “And the hidden treasures of the sand” (Deuteronomy 33:19).

And R. Joseph taught: “Hidden”—this is the hilazon; “treasures” this is the tunny fish; “Sand” this is white glass. Zevulun then said: Master of the Universe, who will inform me? He replied: “There they shall offer sacrifices of righteousness” (ibid). This shall be your sign: Whoever takes from you without payment will not prosper in his business.
