Here "eat and drink" represents having a party and eating a lot of food and drinking a lot of wine. It can be stated clearly that this is what the people were saying. Alternate translation: "You say, 'Let us feast and drink all we want, for we will die soon.'" (See: [[rc://en/ta/man/jit/figs-metonymy]] and [[rc://en/ta/man/jit/figs-explicit]])
