In Isaiah 22:13, the revelers say, "Let us eat and drink, for…"

Answer: Tomorrow we die

When the Lord called for weeping and sackcloth, the people feasted instead, saying, "Let us eat and drink, for tomorrow we die!"

“On that day the Lord GOD of Hosts called for weeping and wailing, for shaven heads and the wearing of sackcloth. But look, there is joy and gladness, butchering of cattle and slaughtering of sheep, eating of meat and drinking of wine: “Let us eat and drink, for tomorrow we die!””— Isaiah 22:12-13 (BSB)
