'Let Us Eat and Drink' in the Bible

But look! Joy and gladness, the killing of oxen and the slaughtering of sheep, the eating of meat and the drinking of wine! "Let us eat and drink, for tomorrow we die!"

If according to a human perspective I fought wild beasts at Ephesus, what benefit [is it] to me? If the dead are not raised, let us eat and drink, for tomorrow we die.
