מדרש על איוב 40:3

Rabba said in the name of R. Jochanan: "The Holy One, praised be He! will make a banquet for the upright from the flesh of the leviathan, as it is said (Ib. 40, 30) Yichru alav Chaverim; yichiu means a banquet, as it is said (II Kings 23) And he prepared (Vayichrch) for them a great meal. Chaverim means scholars, as it is said (Songs 8, 13) Companions (Chaverim) listen for thy voice, etc. And the remainder of it will be cut in pieces, and be sold in the markets of Jerusalem, as it is said (Job 40, 30) Divide him among merchants."
