Musar do Przysłów 9:2

Yalkut Shimoni on Parshat Shoftim understands the repeated reference טבחה, טבחה in Proverbs 9,2, as an allusion to Leviathan and the שור הבר, the "wild ox," auroch, whose meat will be served by G–d to the righteous in the Hereafter (Baba Batra 74b). According to the Aggadah, G–d slaughtered the female Leviathan and salted away its meat in order to serve it in the future at a festive meal for the righteous.
